Is this what you mean: $\frac{\partial }{\partial x}\left [ \frac{e^{\frac{-(x-a)^2}{4y}}}{2\sqrt{y}}\left ( \frac{(x-a)^2}{2y^2} \right )+1 \right ]?$

4. naf Group Title

yup do u know it?

5. across Group Title

I made a mistake, the 1 should be inside the rightmost term.

Partial differentiation is basically the same thing as normal differentiation except that it takes all other variables to be constants. Can you factor out the constans in that expression?

i'll try $1\div2\sqrt{y} and1\div2y ^{2}$

16. naf Group Title

am i wasting ur time?
