Step-by-step explanation: To prove that sinx + cosx / sinx - cosx = tanx + 1 / tanx - 1, we'll simplify both sides of the equation and ... ar = cosx cash y ах and. Sinx, cosx, sinhy, and cosh. كم اكم dr = sinx sunny y are all continuas. - six coshy ay². = sin x coshy. Cosx sinky. are contriers. 하. Do not perform any algebraic simplification yet. Example (cont'd): The function cosx sinx. (. 1. The integration of sin x cos x yields (-1/4) cos 2x + C as the integral of sin x cos x using the sin 2x formula of trigonometry. Apr 27, 2020 ... Geometric interpretation: Rotate the right triangle. The projected length of the √ 2 hypothenuses will vary following a sinusoid. cosxsinx. X+1/4. Xin sinx-cosx. X+π/4. Sin X-cost.
