Hello MHB,
I am working with finding max and min value and I always hesitate when I got absolute value so the one I strugle is to derivate \(\displaystyle |\sin(x+y)|\)
if we do it respect to x is this correct?
\(\displaystyle f_x(x,y)=\frac{\sin(2x)}{2\sqrt{\sin^2(x+y)}}\)\(\displaystyle |\pi\rangle\)
