$2n$ th partial derivative of $\frac{1}{y(1+x^2)-1}$ with respect to $x$.
I need to find the $2n$ th derivative with respect to $x$ of the function $f = \frac{1}{y(1+x^2)-1}$. I tried differentiating util a pattern was founded, but that didn't happen.
I think the $x^2$ is ...

Determine lambda from a non-constant differentiable function of one variable
Suppose f is a non-constant differentiable function of one variable.
Determine, with reasons, the value of $\lambda$ for which
F(x, y) = f($\lambda x^{3}$ + y) satisfies the partial differential ...
