I need help solving the following problem. I have already worked it out, but I am getting stuck on the partial derivative relative to y because I am getting a negative square root somewhere along the way...

Here is the problem: classify the stationary points of:

f(x,y) = -2x + 3y + [ (integral) upperbound = y , lowerbound = x ] e^t^2 dt

I hope it makes sense as written...

Thank you.
