Trigonometric functions for EDecimal

2

Includes sin, cos, tan, asin, acos, atan, atan2. Also including sinh, cosh, tanh should be easy. Here is a starting point: https://github.com/raminrahimzada/CSharp-Helper-Classes/blob/master/Math/DecimalMath/DecimalMath.cs Also doing them for EFloat is okay but...

It is weird that `=`, and `Equals` are defined but not `==` and `!=`.

This is in line with the built-in types which provide non-throwing alternatives of parsing from string.

Excess re-rendering causes waiting times after cell completion

And time to add a new column - arbitrary precision of trig functions cost a lot in performance

**The package I want to suggest the idea to**: AngouriMath Just enabling compilation of matrices.

Simplify inverse trig functions

We can apply our trig constant tables backwards. Inspired by https://github.com/davidedc/Algebrite/issues/111

Solve a pythagorian triple

**The package I want to suggest the idea to**: AngouriMath Solve `a^2 + b^2 = c provided a in ZZ and b in ZZ and c in { 16, 25,...

sqrt(i)=(1+i)/sqrt(2)

**The package I want to suggest the idea to**: AngouriMath `sqrt(i)=(1+i)/sqrt(2)` should simplify to `True` https://www.wolframalpha.com/input/?i=sqrt%28i%29%3D%281%2Bi%29%2Fsqrt%282%29 https://www.youtube.com/watch?v=Z49hXoN4KWg
