This page is used to test the validity of mathematical identities on the complex plane. An initial example is provided:

Identity:

The identity needs to be entered as an expression equal to zero, using the complex operators of Math. The real and imaginary parts must be inspected separately using the selector.

The identity is evaluated in unit increments from -49.5 to 49.5 in both directions on the the complex plane. A green dot indicates that the identity is satisfied within the tolerance of the library, a red dot not. Clear as water...
