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.
