Solution for Cos(x+90)=-sin equation: 


Simplifying
Cos(x + 90) = -1sin

Reorder the terms:
osC(90 + x) = -1sin
(90 * osC + x * osC) = -1sin
(90osC + osxC) = -1sin

Solving
90osC + osxC = -1ins

Solving for variable 'o'.

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

Reorder the terms:
ins + 90osC + osxC = -1ins + ins

Combine like terms: -1ins + ins = 0
ins + 90osC + osxC = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(in + 90oC + oxC) = 0


Subproblem 1
Set the factor 's' equal to zero and attempt to solve:

Simplifying
s = 0

Solving
s = 0

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

Add '-1s' to each side of the equation.
s + -1s = 0 + -1s
Remove the zero:
0 = -1s

Simplifying
0 = -1s
