Solving the first, we have x = 0 + (pi)n. Solving the second, we have. cosx = 1/2. so x = (-pi/6) + 2(pi)n. and x Solve the trig equation, involves using a double angle formula and factoring.Need more help? Mr. Dwyer is available for 1-on-1 tutoring online.

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. 2010-05-18 · sinx (cosx + 2sin²x - 1) = 0. sinx (cosx + 2 (1 - cos²x) - 1) = 0.
