# FP1 - Gradient Functions watch

1. Hi !

Just wanted quick answers for the Gradient Functions (dy/dx) of:
1) Cos
2)Tan
3)Sin
4)ln
5)e^x
6) e^-x

Thanks!

1) -sin
2) sec^2
3) cos
4) 1/x
5) e^x
6) -e^-x
3. 1) -sin(x)
2) sec^2(x) (sec is 1/cos)
3) cos(x)
4) 1/x
5) e^x (This is why we usually use powers of e, is simplifies differentiation and integration)
6) -e^-x
4. Great, Thanks!

1) -sin(x)
2) sec^(x) (sec is 1/cos)
3) cos(x)
4) 1/x
5) e^x (This is why we usually use powers of e, is simplifies differentiation and integration)
6) e^-x
wrong

Incorrect. You ought to be careful on here, if you don't know it's 100% right then don't post...you could cost somebody their grades.

Alternatively, that person could take the initiative to look up the differentials in a textbook. Then this wouldn't be an issue! These are all standard differentials that could be found in any book.

It's exactly what I did before submitting the post, just to double check.
9. Dont worry I noticed the error, thanks anyway!
