<h2>Introduction</h2>
|
||||
|
||||
<p>The <strong>Expression evaluator</strong> is a tool within the <strong>Graphing Calculator</strong> which can compute the result of a typed mathematical expression.</p>
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="start"></a>
|
||||
<h2>Getting started</h2>
|
||||
<p>To evaluate an expression, follow the following steps:</p>
|
||||
<strong>Step 1:</strong> In the application window, click the <em>Evaluate</em> button. <br />
|
||||
<strong>Step 2:</strong> Type an expression in the <em>Input expression</em> field. <br />
|
||||
<strong>Step 3:</strong> Add variables to the variable list if needed.<br />
|
||||
<strong>Step 4:</strong> Click <em>Evaluate</em>. <br />
|
||||
|
||||
<p>Example: </p>
|
||||
<img src="img/eval0.png" style="margin-top: -10px;" />
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="vars"></a>
|
||||
<h2>Variables</h2>
|
||||
|
||||
<p>A description of what variables are, and why they are useful can be found in the <a href="language.htm#vars">language article</a>.</p>
|
||||
|
||||
<p>To use variables in the evaluator window, you need to type the name in the <em>Name</em> field, the value in the <em>Value</em> field, and click <em>Add</em>. If a variable with the same name already exists, you will be prompted if you want to replace the old value.</p>
|
||||
|
||||
<p>The value of a variable can also be an expression, it doesn't have to be a simple number.</p>
|
||||
|
||||
<img src="img/eval1.png" style="margin-top: -10px;" />
|
||||
|
||||
<p>To remove a variable from the list, or edit it, simply right click, and a menu will appear.</p>

<h2>Introduction</h2>
|
||||
|
||||
<p>The <strong>Graphing Calculator</strong> is a tool that can evaluate, plot and integrate expressions (or functions). It includes many useful features, like combining multiple graphs, navigation and zoom controls, and saving plotted expressions.</p>
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="limits"></a>
|
||||
<h2>Limitations</h2>
|
||||
<p>All numeric values are limited to 64bit floating point numbers (approximate range: <20>5.0 <20> 10<sup>-324</sup> to <20>1.7 <20> 10<sup>308</sup>, or 15-16 digits).</p>
|
||||
|
||||
<p>Another limitation is the precision of the graph: if the expression has many vertical asymptotes, it may not be plotted correctly.</p>

|
||||
<h2>Introduction</h2>
|
||||
|
||||
<p>The <strong>Graphing Calculator</strong> evaluates expressions based on a strict set of rules, which form a language. Since the mathematical language is way too complex, and is impossible to write in simple text, this application (and many others) uses a simplified language.</p>
|
||||
|
||||
<p>If you are familiar with programming in a C-like language (C, C++, C#, Java), the language used here is very similar to these programming languages.</p>
|
||||
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="vars"></a>
|
||||
<h2>Variables</h2>
|
||||
<p>A variable is a symbol which may assume any given value. In this application, this symbol is represented by a character string which follows the following rules:</p>
|
||||
<ul>
|
||||
<li>It always begins with a letter.</li>
|
||||
<li>It can only contain letters and numbers, so it cannot contain spaces, underscores and other symbols.</li>
|
||||
<li>Variables are case sensitive. This means that <span style="font-family:Consolas, mono;">alpha</span> is not the same thing as <span style="font-family:Consolas, mono;">Alpha</span>.
|
||||
</ul>
|
||||
|
||||
<p>The advantages of using variables are that you can skip having to type an ugly expression multiple times, and you can reevaluate the expression with a different input easily.</p>
|
||||
|
||||
<p>Variables are supported in the <em>Graphing Calculator</em>, with the limitation that they can only be used in the expression evaluator. Using variables in the plotting of graphs, and integrator is not possible. By default, the only used variable is <em>x</em> when plotting and integrating expressions.</p>
|
||||
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="pvars"></a>
|
||||
<h2>Predefined variables</h2>
|
||||
<p>The evaluator has two predefined variables:</p>
|
||||
<ul>
|
||||
<li><strong>pi</strong> (π)</li>
|
||||
<li><strong>e</strong></li>
|
||||
</ul>
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="ops"></a>
|
||||
<h2>Accepted operators</h2>
|
||||
<p>The following operators are accepted:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>+</strong> (addition)</li>
|
||||
<li><strong>-</strong> (subtraction)</li>
|
||||
<li><strong>*</strong> (multiplication)</li>
|
||||
<li><strong>/</strong> (division)</li>
|
||||
<li><strong>%</strong> (division remainder)</li>
|
||||
<li><strong>^</strong> (power)</li>
|
||||
</ul>
|
||||
|
||||
<p>The order of operations is also respected. A higher order means a higher priority. Operations with the same order are evaluated left to right, with the exception of the power operator.</p>
|
||||
<ul>
|
||||
<li><strong>Order 1:</strong> + -</li>
|
||||
<li><strong>Order 2:</strong> * / %</li>
|
||||
<li><strong>Order 3:</strong> ^</li>
|
||||
</ul>

<h2>Functions</h2>
|

<h2>Syntax rules</h2>
|
||||
|
||||
<p>The syntax of this application is more strict than the mathematic language. These are some of the rules:</p>
|
||||
|
||||
<h3>Numbers: </h3>
|
||||
<ul>
|
||||
<li>Numbers in scientific format are not accepted.</li>
|
||||
<li>Digit grouping is not accepted.</li>
|
||||
<li>The integer and fractional parts of the number must be separated by full stop (.) and <strong>not</strong> comma.</li>
|
||||
|
||||
</ul>
|
||||
|
||||
<h3>Functions:</h3>
|
||||
<ul>
|
||||
<li>The parameter(s) of any functions <strong>must</strong> be enclosed in parantheses. Expressions like <span style="font-family:Consolas, mono;">sin x</span> will fail to evaluate.</li>
|
||||
<li>For functions with multiple parameters, the parameters are separated by comma.</li>
|
||||
<li>The names of functions and variables are case sensitive.</li>
|
||||
</ul>
|
||||
|
||||
<h3>Operators: </h3>
|
||||
<ul>
|
||||
<li>Operators of same precedence (order) are evaluated from left to right, with the exception of the power (^) operator which is evaluated from right to left. Otherwise, precedence rules (order of operations) is respected.</li>
|
||||
<li>Expressions like <span style="font-family:Consolas, mono;">3x</span> are not accepted, you must specify the multiplication operator: <span style="font-family:Consolas, mono;">3*x</span></li>
|
||||
</ul>
|
||||
|
||||
<h3>Others: </h3>
|
||||
<ul>
|
||||
<li>Writing expressions as functions is currently not supported, so the expression <span style="font-family:Consolas, mono;">f(x)=2*x</span> will fail to evaluate. Writing it as <span style="font-family:Consolas, mono;">y=2*x</span> will not work either.</li>

<a name="intro"></a>
|
||||
<h2>Introduction</h2>
|
||||
|
||||
<p>The <strong>Graphing Calculator</strong> evaluates expressions based on a strict set of rules, which form a language. Since the mathematical language is way too complex, and is impossible to write in simple text, this application (and many others) uses a simplified language.</p>
|
||||
|
||||
<p>If you are familiar with programming in a C-like language (C, C++, C#, Java), the language used here is very similar to these programming languages.</p>
|
||||
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="vars"></a>
|
||||
<h2>Variables</h2>
|
||||
<p>A variable is a symbol which may assume any given value. In this application, this symbol is represented by a character string which follows the following rules:</p>
|
||||
<ul>
|
||||
<li>It always begins with a letter.</li>
|
||||
<li>It can only contain letters and numbers, so it cannot contain spaces, underscores and other symbols.</li>
|
||||
<li>Variables are case sensitive. This means that <span style="font-family:Consolas, mono;">alpha</span> is not the same thing as <span style="font-family:Consolas, mono;">Alpha</span>.
|
||||
</ul>
|
||||
|
||||
<p>The advantages of using variables are that you can skip having to type an ugly expression multiple times, and you can reevaluate the expression with a different input easily.</p>
|
||||
|
||||
<p>Variables are supported in the <em>Graphing Calculator</em>, with the limitation that they can only be used in the expression evaluator. Using variables in the plotting of graphs, and integrator is not possible. By default, the only used variable is <em>x</em> when plotting and integrating expressions.</p>
|
||||
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="pvars"></a>
|
||||
<h2>Predefined variables</h2>
|
||||
<p>The evaluator has two predefined variables:</p>
|
||||
<ul>
|
||||
<li><strong>pi</strong> (π)</li>
|
||||
<li><strong>e</strong></li>
|
||||
</ul>
|
||||
</div>
|
||||
|
||||
<div class="section">
|
||||
<a name="ops"></a>
|
||||
<h2>Accepted operators</h2>
|
||||
<p>The following operators are accepted:</p>
|
||||
|
||||
<ul>
|
||||
<li><strong>+</strong> (addition)</li>
|
||||
<li><strong>-</strong> (subtraction)</li>
|
||||
<li><strong>*</strong> (multiplication)</li>
|
||||
<li><strong>/</strong> (division)</li>
|
||||
<li><strong>%</strong> (division remainder)</li>
|
||||
<li><strong>^</strong> (power)</li>
|
||||
</ul>
|
||||
|
||||
<p>The order of operations is also respected. A higher order means a higher priority. Operations with the same order are evaluated left to right, with the exception of the power operator.</p>
|
||||
<ul>
|
||||
<li><strong>Order 1:</strong> + -</li>
|
||||
<li><strong>Order 2:</strong> * / %</li>
|
||||
<li><strong>Order 3:</strong> ^</li>
|
||||
</ul>

<h2>Application crashes at startup</h2>
|
||||
<p>The application needs .NET Framework 4.0 installed. If you don't have it installed, you should download and install it from the <a href="http://www.microsoft.com/download/en/details.aspx?id=17718">Microsoft website</a>.</p>

<a name="graph-incorrect"></a>
|
||||
<h2>Graph is drawn incorrectly</h2>
|
||||
<p>Problems with drawing appear when the function has many vertical asymptothes, or the function changes values too often, and is described <a href="index.htm#limits">here</a>. Try increasing the graph precision from preferences.</p>

<div class="section">

<a name="works-slow"></a>

<h2>Application works slowly</h2>
|

<p>This is a known issue, and has to do with the way the functions are drawn. The slowdown appears when resizing the window, or navigating through the graph. We are working on this issue. What you can try is to decrease the graph precision from the preferences.</p>

<p>You should contact the developer using the contact form. Please, include a useful description of what you were doing when the problem has occured, and eventually a link to a screenshot. The log file which should be located in the directory <em>logs</em>, where the application executable is, would also be very useful.</p>
