Question

how do you find the derivative of f(x)=x/cosx^2 ?

Answer 1

use the quotient rule

Answer 2

lets differentiate each function separately and then apply the quotient rule. Ok ?

Answer 3

do you know the product rule?
we could do it via product rule, or we could explain the quotient rule using product rule

Answer 4

What is the derivative of x?
What is the derivative of cos^2x? (hint: cos^2x = (cos x)^2 )

Answer 5

amorfide, yes we can use a product rule, rewriting the bottom function - cos^(-2)x

Answer 6

lawls say something

Answer 7

i'm sorry but i had to leave for class and just opened up open study right now

Answer 8

the derivative of x is 1 and the derivative of cos^2x is 2cosx * sin(x) by the chain rule?

Answer 9

and the product rule if fg'-gf'/ g^2

Answer 10

i mean the quotient
