Given some input equation, provide a numerical derivative at a given point. The user have a standard text input for the equation and point and the algorithm will provide the numerical derivative along with the steps the algorithm took to derive it. This algorithm will be able to differentiate trigonometric function, logarithmic, and exponentials.

Tetration is broken even if other neighbor x works #56

Closed DragonflyRobotics closed 8 months ago

Just noticed that tetration with x^x breaks. f(x) for x=0.1 is correct with 0.794328234724 but the algorithm gives f'(0.1)=−1.82900835222 while it should be −1.0346801175. Tetrations have a special mathematical property: https://math.stackexchange.com/questions/616014/nth-derivative-of-a-tetration-function

This is a special case for differentiation and far outside the vision statement and won't be fixed.
