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