Simplifying sin(2x) + -1cos(2x) = 0 Remove parenthesis around (2x) ins * 2x + -1cos(2x) = 0 Reorder the terms for easier multiplication: 2ins * x + -1cos(2x) = 0 Multiply ins * x 2insx + -1cos(2x) = 0 Remove parenthesis around (2x) 2insx + -1cos * 2x = 0 Reorder the terms for easier multiplication: 2insx + -1 * 2cos * x = 0 Multiply -1 * 2 2insx + -2cos * x = 0 Multiply cos * x 2insx + -2cosx = 0 Reorder the terms: -2cosx + 2insx = 0 Solving -2cosx + 2insx = 0 Solving for variable 'c'. Move all terms containing c to the left, all other terms to the right. Add '-2insx' to each side of the equation. -2cosx + 2insx + -2insx = 0 + -2insx Combine like terms: 2insx + -2insx = 0 -2cosx + 0 = 0 + -2insx -2cosx = 0 + -2insx Remove the zero: -2cosx = -2insx Divide each side by '-2osx'. c = ino^{-1}Simplifying c = ino^{-1}
