Thus, F (x) = 1/2 x2 is an anti-derivative of ƒ (x) = x. However, if C ... 1/2 ) sin (2x) + C. It may be checked that: d/dx (2 sin (2x) + C) = 2 d/dxsin ... Answer to: Prove that sin x + sin 2x + sin 3x = sin 2x (1 + 2 cos x). By signing up, you'll get thousands of step-by-step solutions to your... Oct 28, 2023 ... sin2x = 2sinxcosx so if you multiply sin2x by 1/2 then you do the same to the other side and so 1/2 times 2sinxcosx is sinxcosx. Therefore 1 ... = ex, y(1) = 2.
