int_(-pi/4)^( pi/4)(x+pi/4)/(2-cos2x)dx

Find the value of int_(pi/4)^(pi/3) (sin2x)/(1-cos2x) dx

int_(-pi/4)^(pi/4)(dx)/(1+cos2x) is

The value of int_(pi/4)^((3pi)/4)(cos x)/(1-cos x)dx is equal to (k-(pi)/(2)) then k=

int_(pi//4)^(pi//2)(dx)/((1-cos2x))

int_(-pi/4)^(pi/4)(dx)/(1+cos2x) is equal to

Evaluate: int_(pi/4)^(pi/3)(dx)/(sin^2x+3cos^2x)

int_(-(pi)/(4))^((pi)/(4))(dx)/(1+cos2x) is

int_(pi//4)^(3pi//4)(dx)/(1+cos x)=

int_(-pi/4)^(pi/4)(secx)/(1+2^(x))dx .

int_0^(pi/4) (cos x- sin x) dx + int_(pi/4)^((5pi)/4) (sinx-cosx) dx + int_(2pi)^(pi/4) (cosx- sinx) dx =
