WebbFrom the Equation (1) we can write it as, x = 1 2 cos - 1 a b 2 x = cos - 1 a b cos 2 x = a b. Substitute cos 2 x = a b in the above Equation (2) y = 2 a b y = 2 b a. Since, π π π π tan π … WebbLet `cos^(-1) (a/b) = 0` Then `cos theta = a/b` L.H.S: `tan {pi/4 + 1/4 cos^(-1) a/b} + tan (pi/4 - 1/2cos^(-1) a/b)` = `tan (pi/4 + theta/2) + tan (pi/4 - theta/2)`
