Question

Find the derivative x^2 + 2tanx

Answer 1

alright, lets break this into parts
can you derivate x^2
and derivate 2tanx? if not I can help

Answer 2

Yup....\[\frac{ d }{dx }x^2 = 2x, \frac{d}{dx}2tanx = 2\sec ^{2}x\]

Answer 3

after chain rule

Answer 4

right, so now unseparate them. you are basically done

Answer 5

So, \[2x+2\sec^{2}x\]?

Answer 6

bingo

Answer 7

Awesome, Thanks!
