描述
While there are genuine use cases when returning "x" would be better (that's what most humans would expect), strictly speaking it is incorrect.
To reproduce in the mathnotepad:
derivative("(x^2)^0.5", "x").evaluate({x:-3})
1
derivative("(x^2)^0.5", "x", {simplify:false}).evaluate({x:-3})
-1
Here I evaluate the same derivative at the same point x=-3 but get two different results.
Same problem for x^4 and I assume all other even powers.
