Solution for (cosx+1)(cosx-1)+sin^2x=0 equation:


Simplifying
(cosx + 1)(cosx + -1) + sin2x = 0

Reorder the terms:
(1 + cosx)(cosx + -1) + sin2x = 0

Reorder the terms:
(1 + cosx)(-1 + cosx) + sin2x = 0

Multiply (1 + cosx) * (-1 + cosx)
(1(-1 + cosx) + cosx(-1 + cosx)) + sin2x = 0
((-1 * 1 + cosx * 1) + cosx(-1 + cosx)) + sin2x = 0
((-1 + 1cosx) + cosx(-1 + cosx)) + sin2x = 0
(-1 + 1cosx + (-1 * cosx + cosx * cosx)) + sin2x = 0
(-1 + 1cosx + (-1cosx + c2o2s2x2)) + sin2x = 0

Combine like terms: 1cosx + -1cosx = 0
(-1 + 0 + c2o2s2x2) + sin2x = 0
(-1 + c2o2s2x2) + sin2x = 0

Solving
-1 + c2o2s2x2 + in2sx = 0

Solving for variable 'c'.

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

Add '1' to each side of the equation.
-1 + c2o2s2x2 + 1 + in2sx = 0 + 1

Reorder the terms:
-1 + 1 + c2o2s2x2 + in2sx = 0 + 1

Combine like terms: -1 + 1 = 0
0 + c2o2s2x2 + in2sx = 0 + 1
c2o2s2x2 + in2sx = 0 + 1

Combine like terms: 0 + 1 = 1
c2o2s2x2 + in2sx = 1

Add '-1in2sx' to each side of the equation.
c2o2s2x2 + in2sx + -1in2sx = 1 + -1in2sx

Combine like terms: in2sx + -1in2sx = 0
c2o2s2x2 + 0 = 1 + -1in2sx
c2o2s2x2 = 1 + -1in2sx

Divide each side by 'o2s2x2'.
c2 = o-2s-2x-2 + -1in2o-2s-1x-1

Simplifying
c2 = o-2s-2x-2 + -1in2o-2s-1x-1

Reorder the terms:
c2 = -1in2o-2s-1x-1 + o-2s-2x-2

Reorder the terms:
c2 + in2o-2s-1x-1 + -1o-2s-2x-2 = -1in2o-2s-1x-1 + in2o-2s-1x-1 + o-2s-2x-2 + -1o-2s-2x-2

Combine like terms: -1in2o-2s-1x-1 + in2o-2s-1x-1 = 0
c2 + in2o-2s-1x-1 + -1o-2s-2x-2 = 0 + o-2s-2x-2 + -1o-2s-2x-2
c2 + in2o-2s-1x-1 + -1o-2s-2x-2 = o-2s-2x-2 + -1o-2s-2x-2

Combine like terms: o-2s-2x-2 + -1o-2s-2x-2 = 0
c2 + in2o-2s-1x-1 + -1o-2s-2x-2 = 0
