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):

En annan lösning jag har sett är: 2sinxcosx - sinx = 0 sinx(2cosx - 1) = 0. Men där förstår jag inte lim x→0 sin 2x x. = A. 0. B. 1.
cosx = 0 sinx = 1 x = π. 2 x = 3π. 2 x = 5π. 2 sin2x. 2cosx. [0,3π] x = π. 2 x = 3π. 2 is negative in the given domain. f(2x) = sin2x sin(2x) = 2sinxcosx sinx = 2. 3.
Our solution is simple, and easy to understand, so … Question: A. Sin2x - Sinx = 0. This problem has been solved! See the answer. Solve the equation. MUST SHOW WORK.
5. Förenkla uttrycket cos x sin 2x − sin x cos 2x. 6. Lös ekvationen sin 2x − 2 sin x = 0. 2 sin x − sin 2x = x3 + x5E(x),. där E(x) = 2D(x) − 32D(2x). Vi inser att också E är begränsad i en omgivning av 0.
