I have a function for which I have calculated:
$\dfrac{d}{dx}f(x,y)=0 $
and
$\dfrac{d}{dy}f(x,y)=2y+\cos(y)$
How can I proceed to calculate the critical points?

Just as with equations in one variable, determine when the partial derivatives become 0. Here, one is already zero so no information there...
But the other one is $2y+\cos(y)=0$. It looks like there isn't a closed form for the solution, so you'd need an approximation...
