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

Consider the following equations (i) cosec^2 x + sec^2 x = cosec^2 x sec^2 x (ii) sec^2 x + tan^2 x = secx tan^2 x (iii) cosec^2 x+ tan^2x = cot^2x + sec^2x Which of the above equations are correct ?

(i) int " x sec"^(2) " 2x dx "" "(ii) int " x sin"^(3) " x dx "

(i) int " x sec"^(2) " 2x dx "" "(ii) int " x sin"^(3) " x dx "

Evaluate: (i) int(sec^(2)x)/(tan x+2)dx (ii) int(2cos2x+sec^(2)x)/(sin2x+tan x-5)dx

The value of int e^(tan x)(x sec^(2)x+sin2x)dx is equal to

The value of int e^(tan x)(x sec^(2)x+sin2x)dx is equal to

f: R rarr R, f(x) = sec^(2)x - tan^(2) x is constant function .

If f(x)=cos ^(2) x+sec ^(2) x , then
