Simplifying sin(2x) * sin(x) + -1cos(2x) * cos(x) = -1cos(x) Remove parenthesis around (2x) ins * 2x * sin(x) + -1cos(2x) * cos(x) = -1cos(x) Reorder the terms for easier multiplication: 2ins * x * ins * x + -1cos(2x) * cos(x) = -1cos(x) Multiply ins * x 2insx * ins * x + -1cos(2x) * cos(x) = -1cos(x) Multiply insx * ins 2i2n2s2x * x + -1cos(2x) * cos(x) = -1cos(x) Multiply i2n2s2x * x 2i2n2s2x2 + -1cos(2x) * cos(x) = -1cos(x) Remove parenthesis around (2x) 2i2n2s2x2 + -1cos * 2x * cos(x) = -1cos(x) Reorder the terms for easier multiplication: 2i2n2s2x2 + -1 * 2cos * x * cos * x = -1cos(x) Multiply -1 * 2 2i2n2s2x2 + -2cos * x * cos * x = -1cos(x) Multiply cos * x 2i2n2s2x2 + -2cosx * cos * x = -1cos(x) Multiply cosx * cos 2i2n2s2x2 + -2c2o2s2x * x = -1cos(x) Multiply c2o2s2x * x 2i2n2s2x2 + -2c2o2s2x2 = -1cos(x) Reorder the terms: -2c2o2s2x2 + 2i2n2s2x2 = -1cos(x) Multiply cos * x -2c2o2s2x2 + 2i2n2s2x2 = -1cosx Solving -2c2o2s2x2 + 2i2n2s2x2 = -1cosx Solving for variable 'c'. Reorder the terms: cosx + -2c2o2s2x2 + 2i2n2s2x2 = -1cosx + cosx Combine like terms: -1cosx + cosx = 0 cosx + -2c2o2s2x2 + 2i2n2s2x2 = 0 Factor out the Greatest Common Factor (GCF), 'sx'. sx(co + -2c2o2sx + 2i2n2sx) = 0Subproblem 1
Set the factor 'sx' equal to zero and attempt to solve: Simplifying sx = 0 Solving sx = 0 Move all terms containing c to the left, all other terms to the right. Add '-1sx' to each side of the equation. sx + -1sx = 0 + -1sx Remove the zero: 0 = -1sx Simplifying 0 = -1sx 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 '(co + -2c2o2sx + 2i2n2sx)' equal to zero and attempt to solve: Simplifying co + -2c2o2sx + 2i2n2sx = 0 Solving co + -2c2o2sx + 2i2n2sx = 0 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.
