First implicitly differentiate the expression with respect to x: $$\frac{d}{dx}\{e^{ax/y}+e^{bx/y}=c\}$$ We can do this in Mathematica: myImplicitDeriv=D[Exp[a x/y[x]] + Exp[b x/y[x]] == c, x] …

First start with the branch points: these are the values of z where the root is not multiple-valued. First: myexp = Together[ TrigToExp[ FullSimplify[(Tanh[z] - Tanh[2 z])^2 + (Tanh[z] Tanh[2 …
