Vi ritar kurvorna y = sin x och y = sin 2x i samma koordinatsystem. Det ser Sätt x + 50° = 0 vilket ger x = - 50°, det vill säga kurvan är förskjuten 50° åt vänster i

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):

In the above therefore either sinx =0 which implies x is 0 or 2cosx -1 =0
