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

yup do u know it?

5. across

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

6. anonymous

yes

7. anonymous

can u do it?

8. across

Of course, but can you?

9. anonymous

So... you just want an answer? Or would you like to know how to solve this?

13. anonymous

yeah i want to know how to solve qns like these

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?

15. anonymous

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

16. anonymous

am i wasting ur time?

17. anonymous

and 1
