2010-08-01 · We know, sin2x = 2sinxcosx. So, sin2x - sinx = 0 . 2sinxcosx - sinx = 0. Then factor out sinx from both (common factor): (sinx) (2cosx-1) = 0. Set the 2 factors (stuff in bracket) equal to 0 and solve for x by checking on your unit circle (x is your cos value, y is your sin value):

Solving the second equation for cos (x) we get: sin (x) = 0 or cos (x) = 1/2. So our solutions are all the angles whose sin is 0 or all the angles whose cos is 1/2. Wolfram|Alpha brings expert-level knowledge and capabilities to the broadest possible range of people—spanning all professions and education levels. sin2x - cos2x = 1 for all values of x : Prove the identity, sin^2x + cos^2x = 1 ?
