Simplifying sen(2x) = 2sen(x) * cos(x) Remove parenthesis around (2x) ens * 2x = 2sen(x) * cos(x) Reorder the terms for easier multiplication: 2ens * x = 2sen(x) * cos(x) Multiply ens * x 2ensx = 2sen(x) * cos(x) Multiply ens * x 2ensx = 2ensx * cos * x Multiply ensx * cos 2ensx = 2cenos2x * x Multiply cenos2x * x 2ensx = 2cenos2x2 Solving 2ensx = 2cenos2x2 Solving for variable 'e'. Move all terms containing e to the left, all other terms to the right. Add '-2cenos2x2' to each side of the equation. -2cenos2x2 + 2ensx = 2cenos2x2 + -2cenos2x2 Combine like terms: 2cenos2x2 + -2cenos2x2 = 0 -2cenos2x2 + 2ensx = 0 Factor out the Greatest Common Factor (GCF), '2ensx'. 2ensx(-1cosx + 1) = 0 Ignore the factor 2.Subproblem 1
Set the factor 'ensx' equal to zero and attempt to solve: Simplifying ensx = 0 Solving ensx = 0 Move all terms containing e to the left, all other terms to the right. Simplifying ensx = 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 '(-1cosx + 1)' equal to zero and attempt to solve: Simplifying -1cosx + 1 = 0 Reorder the terms: 1 + -1cosx = 0 Solving 1 + -1cosx = 0 Move all terms containing e to the left, all other terms to the right. Add '-1' to each side of the equation. 1 + -1 + -1cosx = 0 + -1 Combine like terms: 1 + -1 = 0 0 + -1cosx = 0 + -1 -1cosx = 0 + -1 Combine like terms: 0 + -1 = -1 -1cosx = -1 Add 'cosx' to each side of the equation. -1cosx + cosx = -1 + cosx Combine like terms: -1cosx + cosx = 0 0 = -1 + cosx Simplifying 0 = -1 + cosx 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.
