<evaluate/>

<evaluate/> is a Math Operator component which renders the result of a <function>evaluated at a specified input parameter or parameters. This is a self-closing tag; it’s tempting to try to nest the function within opening and closing tags, but this is incorrect — the function to be evaluated must instead be specified within the function attribute directly.

Attributes and Properties

Example: <evaluate/> a function at a user-input

The two required attributes for the <evaluate/> component are function and input.

Example: <evaluate/> - the shortcut

The shortcut macro for the evaluate component is $$function(input).

Attribute Example: function

<function name="g">sin(x)</function>
<p><m>g(\frac{\pi}{3})</m> = <evaluate function="$g" input="pi/3"/></p>     

The function attribute specifies a target function to evaluate.

Attribute Example: input

<function name="h">e^x</function>
<p><m>h(y)</m> = <evaluate function="$h" input="y"/></p>  

The input attribute specifies an input at which to evaluate the function.

Attribute Example: forceNumeric

The forceNumeric attribute forces a numerical evaluation of the function.
