Solution for cos(x)+cos^2(x)-sin^2(x)=0 equation: 


Simplifying
cos(x) + cos2(x) + -1sin2(x) = 0

Multiply cos * x
cosx + cos2(x) + -1sin2(x) = 0

Multiply cos2 * x
cosx + cos2x + -1sin2(x) = 0

Multiply in2s * x
cosx + cos2x + -1in2sx = 0

Solving
cosx + cos2x + -1in2sx = 0

Solving for variable 'c'.

Move all terms containing c to the left, all other terms to the right.

Add 'in2sx' to each side of the equation.
cosx + cos2x + -1in2sx + in2sx = 0 + in2sx

Combine like terms: -1in2sx + in2sx = 0
cosx + cos2x + 0 = 0 + in2sx
cosx + cos2x = 0 + in2sx
Remove the zero:
cosx + cos2x = in2sx

Combine like terms: in2sx + -1in2sx = 0
cosx + cos2x + -1in2sx = 0

Factor out the Greatest Common Factor (GCF), 'sx'.
sx(co + cos + -1in2) = 0


Subproblem 1
