# how to diffeniate this

Announcements Posted on
Why bother with a post grad? Are they even worth it? Have your say! 26-10-2016
1. cos(e^xy).y(e^xy)

with respect to x

Tried for 1hr
2. "diffenciate" ?
3. You cant differentiate that, it's not an equation

Implicit differentiation.
5. Thats not possible. Theres too many variables, thats not taught in A-Level.

It is A level.

Yes it is.

First use product rule to give
then differentiate implicitly.
Remember that .

I got the answer to be:

Someone verify; I dont even care if I'm wrong. Slap whoever gave you this. Good night and good luck with it!

12. Ay I solved it, last night's attempt was incorrect.

it's so ez op, primary school stuff, pffft
Spoiler:

There should be a closing square bracket at the very end, not sure why it's not showing.

It always gives answers doesnt it.
So i thought if it guves solutions i just use it on this and answer will come.

Don't forget the plus and minus signs when square rooting then you should get some very neat answers to this indeed.

I guess you disagree with d/dx (x) = 1 then? Since x isn't an equation...

Honestly.

Wrong. It is.

Theres too many variables
Wrong. There isn't.

thats not taught in A-Level.
Wrong. It is.

i was just going off the fact that there is no equal sign

Why do you assume there must be an equals sign?
