Explanation: I hope that the Problem is : Prove : cos2A1−tanA+sin3AsinA−cosA=1+sinAcosA. We have, cos2A1−tanA+sin3AsinA−cosA ,. =cos2A1−sinAcosA ... α. Cos ox. 11- cas²α sind. Sia cosa sina. Cosa.

We use the sin2A formula to derive the formula for sinA cosA. It is equal ... Jul 23, 2018 ... The value of Sin A + Cos A actually depends on the variable 'a' so we can not actually prodict out the exact answer to this question. Dec 17, 2020 ... Calculation: (sinA + cosA)/(sinA – cosA) = 5/4 ⇒ 4(sin A + cos A) = 5(sin A – cos A) ⇒ 4sinA + 4cosA = 5sinA – 5cosA ⇒ :I sina cosa. In subsection 2, R was defined as the radius of curvature at point x, is the curvature at the mid-point of the geodesic. Generally these two ... Definition of Sec and Tan = 1/Cos2A - Sin2A/Cos2A Combining Fractions = (1 - Sin2A) / (Cos2A) Apply Double Angle Formula = (1 - 2SinACosA Prove that: (cosA - sinA + 1) / (cosA + sinA +1) = (1 - sinA) / cosA. Answer: For solving this questions we need to rationalize the denominator.
