How can you prove that (cos^2 A-sin^2 B) / (sinA cosA+sinB cosB) =cot(A+B)? The RHS should be cot(A+B). Nov 11, 2015 ... ... cosA cosB - sinA sin B. 15:14, Some of you learned this mysterious formula back, last time you took trigonometry And of course if you took ... Prove that: (cosA - sinA + 1) / (cosA + sinA +1) = (1 - sinA) / cosA. Answer: For solving this questions we need to rationalize the denominator. term sina cosa is symmetric with respect to a=45°. We therefore expect that the transverse voltage for a 30° and 60° should be the same. This is definitely ... ... Cosa'≈1.0, Sina' ≈ 0 and equation 22 reduces to. 1.146 (Y¸-y) tano. С2. V. 2.
