If cos x + sec x=−2 for a positive odd integer n then cos^n x+sec^n x is

Let f(x)=|sec x cos x sec^(2)x+cot x cos ecx cos^(2)x cos^(2)x cos ec^(2)x1cos^(2)x cos^(2)x Prove that int_(0)^((pi)/(2))f(x)dx=-(pi)/(4)-(8)/(15)

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

Solve the following differential equation:- (d^2y)/(dx^2)= 4e^x + x cos x + sec^2x Given that y(0) = 2, y' (0) = 4 .

The solution of the differential equation cos y log(sec x+tan x)dx=cos x log(sec y+tan y)dy is (a) sec^(2)x+sec^(2)y=c(b)sec x+sec y=c(c)sec x-sec y=c(d)Non of these
