FreePre-Algebra, Algebra, Trigonometry, Calculus, Geometry, Statistics and Chemistry calculators step-by-step Whatis a Cos 2X? The trigonometric ratios of an angle in a right triangle define the relationship between the angle and the length of its sides. Cosine 2X or Cos 2X is also, one such trigonometrical formula, also known as double angle formula, as it has a double angle in it. Because of this, it is being driven by the expressions for Takingsquare root on both sides. cosx + sinx = sinx ± √1 - sin 2 x. By using the cofunction or complement identity. cosx = sin (π/2 - x) sinx + cosx = sinx + sin (π/2 - x) Therefore, when asked What is sin x + cos x in terms of sine? then the answer will be sin x + cos x in terms of sine is sinx + sin (π/2 - x).
