Simplifying 3cos(x) + 3cos(x) * sin(x) = 0 Multiply cos * x 3cosx + 3cos(x) * sin(x) = 0 Multiply cos * x 3cosx + 3cosx * ins * x = 0 Multiply cosx * ins 3cosx + 3cinos2x * x = 0 Multiply cinos2x * x 3cosx + 3cinos2x2 = 0 Reorder the terms: 3cinos2x2 + 3cosx = 0 Solving 3cinos2x2 + 3cosx = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Factor out the Greatest Common Factor (GCF), '3cosx'. 3cosx(insx + 1) = 0 Ignore the factor 3.Subproblem 1
Set the factor 'cosx' equal to zero and attempt to solve: Simplifying cosx = 0 Solving cosx = 0 Move all terms containing c to the left, all other terms to the right. Simplifying cosx = 0 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 '(insx + 1)' equal to zero and attempt to solve: Simplifying insx + 1 = 0 Reorder the terms: 1 + insx = 0 Solving 1 + insx = 0 Move all terms containing c to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + insx = 0 + -1 Combine like terms: 1 + -1 = 0 0 + insx = 0 + -1 insx = 0 + -1 Combine like terms: 0 + -1 = -1 insx = -1 Add '-1insx' to each side of the equation. insx + -1insx = -1 + -1insx Combine like terms: insx + -1insx = 0 0 = -1 + -1insx Simplifying 0 = -1 + -1insx 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.
