To successfully use this tool you must follow these rules on how to construct
your equations.

Operators:
 *  multiplication
 /  division
 +  plus
  minus
 ( )  brackets
 ^  power e.g $ x^2 $ = x^2


You must enter all operators. For example $ 2x+3 $ would be
2*x+3, note that you must show the multiplication sign.

If you have a fraction like $ \frac{2x+3}{3x+9} $
you must enter both numerator and denominator in brackets, so the
above function would become (2*x+3)/(3*x+9)

Builtin functions:
 $sin(x)$, $cos(x)$, $tan(x)$  Trigonometric functions.
 $asin(x)$, $acos(x)$, $atan(x)$  Inverse Trigonometric functions.
 $sinh(x)$, $cosh(x)$, $tanh(x)$  Hyperbolic Trigonometric functions.
 $log(x)$  Natural Logarithm.
 $log10(x)$  Log base 10
 $exp(x)$  exponential, e^{x}


You can put functions within builtin functions for example
$ sin(2x+x^2) $ would be sin(2*x+x^2)
