Question

solve for:
d/ dx-> sin^2 (x) - 2 sin x - 3

Answer 1

Do you want f(x) or f'(x) = 0 or what?

Answer 2

ok its 2 sin x cos x - 2 cos x

Answer 3

is it equal to 0?

Answer 4

yes, it's equal to zero

Answer 5

ok, then 2sinx cos x - 2 cos x = 0 after finding d/dx

Answer 6

therefore, 2 sinx cos x = 2 cos x

Answer 7

u can cancel out the 2s and a cos x from both sides of the equation

Answer 8

hence we get, sinx = 1

Answer 9

x = pi/2

Answer 10

does it look good?

Answer 11

was the answer alright?

Answer 12

yes, I couldn't figure it out after I found the derivative, so thnx
