Find the general solution for each of the following equations:

sin2x + cosx = 0


given equation is sin2x + cos x= 0


2 sin x cos x + cos x = 0 ( sin 2A = 2 sin A cosA)


cos x (2 sin x + 1) = 0


cos x = 0 or 2sin x +1 = 0


Now cos x = 0



And 2 sin x + 1= 0




the general solution of the equation is
