### An issue concerning the NMaximize command in Mathematica

I have two sets. One set consists of constants and the other one consists of expressions depending on two variables "a" and "b". I find absolute values of correlations between the ...

### Maximize a function of $x$ and $y$ where $x^2 +y^2 \leq 1$

I have the following function: $f(x,y) = x(y^2-x^2)- \frac{(x^2 +y^2)^2}{2\rho}+\frac{3x^2(y^2-4x^2)}{\rho}$ where $\rho>0$ is a constant. My goal is to find the maximum value of this function ...
