Question

find the derivative of 2sinx-tanx

Answer 1

\[\Large y = 2sinx-tanx\]
Do you know the derivative of sinx, and can you find the derivative of tan x? That's all you need here.

Answer 2

yes it is cosx

Answer 3

and the derivative of tanx is sec^2x

Answer 4

So what's the problem you have then? All you have to do is put it all together... the constants just stay where they are.

Answer 5

well if i just take the derivative of both the equation becomes 2cosx-sec^2

Answer 6

do i need to simplify

Answer 7

And that's correct.

Answer 8

thats it no more

Answer 9

Yep.

Answer 10

ok thanks
