int_(1)^( pi)(7sec x tan x)/(4sec^(3)x)dx=(pi^(2))/(4)

int_(0)^( pi)(x sec x tan x)/(1+sec^(2)x)dx=(pi^(2))/(4)

Using properties of definite integrals,prove the following : int_(o)^( pi)(x tan x)/(sec x csc x)dx=(pi^(2))/(4)

int_(0)^( pi)(x tan x)/(sec x+cos x)dx is (pi^(2))/(4)(b)(pi^(2))/(2)(c)(3 pi^(2))/(2) (d) (pi^(2))/(3)

int_(0)^( pi)(x tan x)/(tan x+sec x)*dx=(pi(pi-2))/(2)

int_(0)^( pi)x(tan x)/(sec x+cos x)dx=(pi^(2))/(4)

If int_(0)^( pi)((2x+3)sec x tan x)/(4+tan^(2)x)dx=((p pi+q)pi)/(3sqrt(3)) then p+q=

Evaluate int_(0)^(pi/(3))(sec x tan x)/(1+sec^(2)) x dx

int_(0)^( pi)((ax+b)sec x tan x)/(4+tan^(2)x)dx(a,b>0)
