Using the Chain Rule :
derivative of (sinx)2 = 2(sinx)1 * (derivative of sinx)
d/dx (Sinx)2 = 2(sinx)1 * [d/dx (Sinx)]
d/dx (Sinx)2 = 2(sinx) * (cosx)
d/dx (Sinx)2 = 2 (sinx) * (cosx)
d/dx (Sinx)2 = 2 sin(x) * cos(x)

Do you mean sin(x2) or sin(x)2?
In each case, you would apply the chain rule. The derivative of the sine function is the cosine, and the derivative with respect to x of axn is nax(n - 1).
So if you mean:
f(x) = sin(x2)
Then:
f'(x) = cos(x2) * 2x
If you mean:
f(x) = sin(x)2
Then:
f'(x) = 2sin(x) * cos(x)
6,561 (i solved it by using this sentence: (9x9) x (9x9)= 81x81=6,561
.5(x-sin(x)cos(x))+c
Cosine squared theta = 1 + Sine squared theta
No. Cos squared x is not the same as cos x squared. Cos squared x means cos (x) times cos (x) Cos x squared means cos (x squared)
cosx^2 differentiates too 2(cosx)^1 x the differential of cos which is -sin so u get -2sinxcosx use the chain rule!
