Simplifying 2tan(x) * cos(x) + 2cos(x) = tan(x) + 1 Multiply ant * x 2antx * cos * x + 2cos(x) = tan(x) + 1 Multiply antx * cos 2acnostx * x + 2cos(x) = tan(x) + 1 Multiply acnostx * x 2acnostx2 + 2cos(x) = tan(x) + 1 Multiply cos * x 2acnostx2 + 2cosx = tan(x) + 1 Multiply ant * x 2acnostx2 + 2cosx = antx + 1 Reorder the terms: 2acnostx2 + 2cosx = 1 + antx Solving 2acnostx2 + 2cosx = 1 + antx Solving for variable 'a'. Move all terms containing a to the left, all other terms to the right. Add '-1antx' to each side of the equation. 2acnostx2 + -1antx + 2cosx = 1 + antx + -1antx Combine like terms: antx + -1antx = 0 2acnostx2 + -1antx + 2cosx = 1 + 0 2acnostx2 + -1antx + 2cosx = 1 Add '-2cosx' to each side of the equation. 2acnostx2 + -1antx + 2cosx + -2cosx = 1 + -2cosx Combine like terms: 2cosx + -2cosx = 0 2acnostx2 + -1antx + 0 = 1 + -2cosx 2acnostx2 + -1antx = 1 + -2cosx Reorder the terms: -1 + 2acnostx2 + -1antx + 2cosx = 1 + -2cosx + -1 + 2cosx Reorder the terms: -1 + 2acnostx2 + -1antx + 2cosx = 1 + -1 + -2cosx + 2cosx Combine like terms: 1 + -1 = 0 -1 + 2acnostx2 + -1antx + 2cosx = 0 + -2cosx + 2cosx -1 + 2acnostx2 + -1antx + 2cosx = -2cosx + 2cosx Combine like terms: -2cosx + 2cosx = 0 -1 + 2acnostx2 + -1antx + 2cosx = 0 The solution to this equation could not be determined.
