Solution for sin(2x-30)=cos(3x+40) equation: 


Simplifying
sin(2x + -30) = cos(3x + 40)

Reorder the terms:
ins(-30 + 2x) = cos(3x + 40)
(-30 * ins + 2x * ins) = cos(3x + 40)
(-30ins + 2insx) = cos(3x + 40)

Reorder the terms:
-30ins + 2insx = cos(40 + 3x)
-30ins + 2insx = (40 * cos + 3x * cos)
-30ins + 2insx = (40cos + 3cosx)

Solving
-30ins + 2insx = 40cos + 3cosx

Solving for variable 'i'.

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

Combine like terms: 40cos + -40cos = 0
-40cos + -3cosx + -30ins + 2insx = 0 + 3cosx + -3cosx
-40cos + -3cosx + -30ins + 2insx = 3cosx + -3cosx

Combine like terms: 3cosx + -3cosx = 0
-40cos + -3cosx + -30ins + 2insx = 0

Factor out the Greatest Common Factor (GCF), 's'.
s(-40co + -3cox + -30in + 2inx) = 0


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

Simplifying
s = 0

Solving
s = 0

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

Subproblem 2
Set the factor '(-40co + -3cox + -30in + 2inx)' equal to zero and attempt to solve:

Simplifying
-40co + -3cox + -30in + 2inx = 0

Solving
-40co + -3cox + -30in + 2inx = 0

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

Add '40co' to each side of the equation.
-40co + -3cox + -30in + 40co + 2inx = 0 + 40co

Reorder the terms:
-40co + 40co + -3cox + -30in + 2inx = 0 + 40co

Combine like terms: -40co + 40co = 0
0 + -3cox + -30in + 2inx = 0 + 40co
-3cox + -30in + 2inx = 0 + 40co
Remove the zero:
-3cox + -30in + 2inx = 40co

Add '3cox' to each side of the equation.
-3cox + -30in + 3cox + 2inx = 40co + 3cox

Reorder the terms:
-3cox + 3cox + -30in + 2inx = 40co + 3cox

Combine like terms: -3cox + 3cox = 0
0 + -30in + 2inx = 40co + 3cox
-30in + 2inx = 40co + 3cox
