Solution for Sin(2x+30)=cos(3x+20) equation:


Simplifying
Sin(2x + 30) = cos(3x + 20)

Reorder the terms:
inS(30 + 2x) = cos(3x + 20)
(30 * inS + 2x * inS) = cos(3x + 20)
(30inS + 2inxS) = cos(3x + 20)

Reorder the terms:
30inS + 2inxS = cos(20 + 3x)
30inS + 2inxS = (20 * cos + 3x * cos)
30inS + 2inxS = (20cos + 3cosx)

Solving
30inS + 2inxS = 20cos + 3cosx

Solving for variable 'i'.

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

Reorder the terms:
-20cos + -3cosx + 30inS + 2inxS = 20cos + 3cosx + -20cos + -3cosx

Reorder the terms:
-20cos + -3cosx + 30inS + 2inxS = 20cos + -20cos + 3cosx + -3cosx

Combine like terms: 20cos + -20cos = 0
-20cos + -3cosx + 30inS + 2inxS = 0 + 3cosx + -3cosx
-20cos + -3cosx + 30inS + 2inxS = 3cosx + -3cosx

Combine like terms: 3cosx + -3cosx = 0
-20cos + -3cosx + 30inS + 2inxS = 0
