Prove that sec8x-1/sec4x-1 tan8x/tan2x
Webb(sec8x - 1) / (sec4x - 1) = tan8x/______ View Answer Answer & Explanation Solution: (sec8x - 1) / (sec4x - 1) By taking LCM = (1 - cos8x) cos4x / (1 - cos4x) cos8x Now, (1-cos2x) = 2*(sinx)^2 Thus, = 2*(sin4x)^2*cos4x / 2*(sin2x)^2*cos8x )] =sin4x (2sin4xcos4x) / 2*(sin2x)^2*cos8x = (2sin2xcos2x) sin8x / (2sin2xsin2x) cos8x Webb1 HOLIDAYS HOME WORK CLASS XI B (2024-19) ENGLISH NOTICES ...

Webb8 apr. 2024 · Hint: To solve such questions, we take either the left hand side of the equation or right hand side of the equation and simplify it till we reach the term written in the other side. Here we take the LHS side of the equation and try to convert it into sin and cos functions, so that we can convert it into tan function easily.
Webb30 okt. 2024 · During my math class of yesterday, our teacher asked us to prove the following: 1 + tan 2 ( x) = sec 2 ( x) [Or if you prefer, sec 2 ( x) = 1 / cos 2 ( x)] And the teacher has forbidden us to use trigonometric entities except for the basic ones (sin (x), cos (x) and tan (x)). So, he pretty much wants us to derive it from a mere triangle.

WebbWe know that 8x = 6x + 2x. Therefore, tan ( 8 x) = tan ( 6 x + 2 x) ⇒ tan ( 8 x) = tan 6 x + tan 2 x 1 − tan 6 x tan 2 x. ⇒ tan 8 x − tan 8 x tan 6 x tan 2 x = tan 6 x + tan 2 x. ⇒ tan 8 x − tan 6 x − tan 2 x = tan 8 x tan 6 x tan 2 x. Hence proved. Concept: Trigonometric Functions of Sum and Difference of Two Angles.

Since the first factor, (sec2x − tan2x) = ( 1 cos2x − sin2x cos2x) =. = 1 −sin2x cos2x = cos2x cos2x = 1. There for, the left side becomes; LS = (sec2x +tan2x), and it equals the right side.
