If (cos x+sin x) / cos^3 x= a tan^3x - b tan^2 x + c tan x +d, find a+b+c+d.

If (cos x+sin x) / cos^3 x= a tan^3x - b tan^2 x + c tan x +d, find a+b+c+d.

  1. Find the value of Sinx+cosx/cos³x
  2. If a Sinx =b cosx=2ctanx/1-tan²x then (a²-b²)²/a²+b²
  3. Given Sinx/a= cosx/b= tanx/c= k  then                    bc, a²+b², 1/ck+ak/1+bk,a²+b²+c²
