Verify by differentiation that: \[\LARGE \int (cos^3x)dx=sinx-\frac{1}{3}sin^3x+C\]

OpenStudy (isaiah.feynman):

Simply differentiate \[\frac{ 1 }{ 3 } \sin^{3}x\]

OpenStudy (luigi0210):

I never did understand how to differentiate with trig functions that have exponents. Could you walk me through it? .-.

OpenStudy (inkyvoyd):

use the chain rule. For d/dx f(u) take f'(u)u'

OpenStudy (inkyvoyd):

you will have to play with the trigonometric identities (I see a bit of sin^2 x+cos^2 x=1 in this one) to get what you want.

OpenStudy (isaiah.feynman):

I leave it to inkyvod

OpenStudy (primeralph):

Why bother?

OpenStudy (isaiah.feynman):

The silhouette man is here.
