Version: 1.4.1
Explanation: Enter the equation that needs to be displayed. The
usual math function can be used: +.-.*,/,(,), abs(), acos(), asin(), atan(), atan2(), cos(), exp(), log(), pow(), sin(), sqrt(), tan().
Note for x^3 used the pow(x,3) notation.
If you need integration as well, checkmark on one or more integration methods.
For fastest and most accurate method use Fox-Romberg or Gauss.
For accuracy the methods takes it to the numeric limits, however to avoid time
consuming operations the limits on number function evaluation is around 65536
calls.
Note: Gauss-Chebyshev required that the function is on the form f(x)/sqrt(1-x^2)
otherwise result are incorrect. Gauss-Hermite required that the function is on
the form e-x^2*f(x).
The Test button setup a default equation (for testing only). Note that the
interval [0,0.5] contains a singularity for x=0 making it hard for Trapez,
Simpson and Romberg method to get a high accuracy on the result. Fox-Romberg can
handle this to the numeric limit!
