Simplifying 4cosx + -8sinx * cosx = 0 Multiply insx * cosx 4cosx + -8cinos2x2 = 0 Reorder the terms: -8cinos2x2 + 4cosx = 0 Solving -8cinos2x2 + 4cosx = 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), '4cosx'. 4cosx(-2insx + 1) = 0 Ignore the factor 4.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 '(-2insx + 1)' equal to zero and attempt to solve: Simplifying -2insx + 1 = 0 Reorder the terms: 1 + -2insx = 0 Solving 1 + -2insx = 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 + -2insx = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -2insx = 0 + -1 -2insx = 0 + -1 Combine like terms: 0 + -1 = -1 -2insx = -1 Add '2insx' to each side of the equation. -2insx + 2insx = -1 + 2insx Combine like terms: -2insx + 2insx = 0 0 = -1 + 2insx Simplifying 0 = -1 + 2insx 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.
