Ive got Imageshack - dxdy.jpg for the first two questions. Are they correct? I dont know how to do the 3rd and 4th parts. also is the denominator corect?
here is the q again- bigger

So the function is $\displaystyle f(x,y)= \frac{sin(e^x+ y^2)}{\sqrt{x- y}}$ and you are asked to find the first and second partial derivatives with respect to x and y.
That is tedious but straight forward. What have you done and where did you hit a snag?
For the first two questions I got - Imageshack - dxdy.jpg
for the 3rd part I've multiplied the answer to the first part by 2(x-y)^1/2. Then I differatiated to get upto here so far Imageshack - 53381968.jpg. Im not sure if Im correct could you possibly check please?
