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 and log() is the natural logarithm
If you need integration as well, checkmark on one or more integration methods.
For fastest and most accurate method use Fox-Romberg, Double exponential 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
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!
