Question about SoftMath Algebrator - Algebra Homework Solver (689076614429)
Hii..this can be done as follow
cos^2 x = 1 - sin^2 x--------(1)
2cos^2 x=1+ sin x
2cos^2 x - sin x -1=0
Substituting formula (1)
2(1 - sin^2 x) - sin x - 1 = 0
2sin^2 x + sin x - 1 = 0
(2 sin x - 1)(sin x +1) = 0
2 sin x - 1 = 0 or sin x +1 = 0
sin x = 1, and sin x = -1
