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

yup do u know it?

5. across

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

6. naf

yes

7. naf

can u do it?

8. across

Of course, but can you?

9. naf

my teacher said it would take half an hour to do it nope idk

10. naf

i tried but forgot everything about differentiation

11. naf

please give me d ans it's not some homework that i'm trying 2 copy

12. across

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

13. naf

yeah i want to know how to solve qns like these

14. across

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. naf

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

16. naf

am i wasting ur time?

17. naf

and 1

18. naf

sosweet?
