Solution for sin(x+20)=cos(x) equation: 


Simplifying
sin(x + 20) = cos(x)

Reorder the terms:
ins(20 + x) = cos(x)
(20 * ins + x * ins) = cos(x)
(20ins + insx) = cos(x)

Multiply cos * x
20ins + insx = cosx

Solving
20ins + insx = cosx

Solving for variable 'i'.

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

Reorder the terms:
-1cosx + 20ins + insx = cosx + -1cosx

Combine like terms: cosx + -1cosx = 0
-1cosx + 20ins + insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(-1cox + 20in + inx) = 0


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

Simplifying
s = 0
