Derivatives

Sep 3, 2026

Fixed: exp(x), cosh(x), arcsin(x), arctan(x), tanh(x) and cotan(x) no longer crash the screen.

Fixed: the derivative of an inverse function applied to a fraction, such as arcsin(x/2), was wrong.

Fixed: x²/(2x) simplified to 1, and x/2 − x/2 to x.

Powers of functions are now written sin²x, as in textbooks, instead of (sin x)².
