Web add 1 1 to both sides of the equation. Compute answers using wolfram's breakthrough technology & knowledgebase, relied on. Web add 1 1 to both sides of the equation. My notebook, the symbolab way. Cos(x) = ±1 cos ( x) = ± 1 the complete solution is the result of both the positive and negative portions of the solution. Cos(2x) = cos(x+x) = cosxcosx −sinxsinx = cos2x −sin2x = cos2x −(1−cos2x) = 2cos2 x−1 so, cos2x = 21+cos(2x) which can be substituted. Web 1,709 11 23. Cos2(x) = 1 cos 2 ( x) = 1 take the square root of both sides of the equation to eliminate the exponent on the left side. Sin (x/2) proof half angle formula: Cos(x) = 1 2 cos ( x) = 1 2.
