If `sec A+tan A=x` then `sec A=` `(x^2-1)/x`

If sec theta+tan theta=x, then sec theta=(a)(x^(2)+1)/(x) (b) (x^(2)+1)/(2x)(c)(x^(2)-1)/(2x) (d) (x^(2)-1)/(x)

If sec x=x+(1)/(4x) then sec x+tan x

Evaluate : int sec x tan x sqrt(4 sec^(2) x- 1) dx

Evaluate : int sec x tan x sqrt(4 sec^(2) x- 1 dx)
