Simplifying Sin(5x + 3) = cos(2x + 9) Reorder the terms: inS(3 + 5x) = cos(2x + 9) (3 * inS + 5x * inS) = cos(2x + 9) (3inS + 5inxS) = cos(2x + 9) Reorder the terms: 3inS + 5inxS = cos(9 + 2x) 3inS + 5inxS = (9 * cos + 2x * cos) 3inS + 5inxS = (9cos + 2cosx) Solving 3inS + 5inxS = 9cos + 2cosx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Reorder the terms: -9cos + -2cosx + 3inS + 5inxS = 9cos + 2cosx + -9cos + -2cosx Reorder the terms: -9cos + -2cosx + 3inS + 5inxS = 9cos + -9cos + 2cosx + -2cosx Combine like terms: 9cos + -9cos = 0 -9cos + -2cosx + 3inS + 5inxS = 0 + 2cosx + -2cosx -9cos + -2cosx + 3inS + 5inxS = 2cosx + -2cosx Combine like terms: 2cosx + -2cosx = 0 -9cos + -2cosx + 3inS + 5inxS = 0 The solution to this equation could not be determined.
