Simplifying sin(2x + 8) = cos(5x + -9) Reorder the terms: ins(8 + 2x) = cos(5x + -9) (8 * ins + 2x * ins) = cos(5x + -9) (8ins + 2insx) = cos(5x + -9) Reorder the terms: 8ins + 2insx = cos(-9 + 5x) 8ins + 2insx = (-9 * cos + 5x * cos) 8ins + 2insx = (-9cos + 5cosx) Solving 8ins + 2insx = -9cos + 5cosx Solving for variable 'i'. Move all terms containing i to the left, all other terms to the right. Reorder the terms: 9cos + -5cosx + 8ins + 2insx = -9cos + 5cosx + 9cos + -5cosx Reorder the terms: 9cos + -5cosx + 8ins + 2insx = -9cos + 9cos + 5cosx + -5cosx Combine like terms: -9cos + 9cos = 0 9cos + -5cosx + 8ins + 2insx = 0 + 5cosx + -5cosx 9cos + -5cosx + 8ins + 2insx = 5cosx + -5cosx Combine like terms: 5cosx + -5cosx = 0 9cos + -5cosx + 8ins + 2insx = 0 Factor out the Greatest Common Factor (GCF), 's'. s(9co + -5cox + 8in + 2inx) = 0Subproblem 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. Add '-1s' to each side of the equation. s + -1s = 0 + -1s Remove the zero: 0 = -1s Simplifying 0 = -1s The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined.Subproblem 2
Set the factor '(9co + -5cox + 8in + 2inx)' equal to zero and attempt to solve: Simplifying 9co + -5cox + 8in + 2inx = 0 Solving 9co + -5cox + 8in + 2inx = 0 Move all terms containing i to the left, all other terms to the right. Add '-9co' to each side of the equation. 9co + -5cox + 8in + -9co + 2inx = 0 + -9co Reorder the terms: 9co + -9co + -5cox + 8in + 2inx = 0 + -9co Combine like terms: 9co + -9co = 0 0 + -5cox + 8in + 2inx = 0 + -9co -5cox + 8in + 2inx = 0 + -9co Remove the zero: -5cox + 8in + 2inx = -9co Add '5cox' to each side of the equation. -5cox + 8in + 5cox + 2inx = -9co + 5cox Reorder the terms: -5cox + 5cox + 8in + 2inx = -9co + 5cox Combine like terms: -5cox + 5cox = 0 0 + 8in + 2inx = -9co + 5cox 8in + 2inx = -9co + 5cox The solution to this equation could not be determined. This subproblem is being ignored because a solution could not be determined. The solution to this equation could not be determined.
