int_(0)^( pi/2)(dx)/(2+cos x)

Evaluate the following integral: int_(0)^( pi/2)(dx)/(4cos x+2sin x)

Consider the integral int_(0)^(2 pi)(dx)/(5-2cos x) making the substitution tan((x)/(2))=t, we have I=int_(0)^(2 pi)(dx)/(5-2cos x)=int_(0)^(0)(2dt)/((1+t^(2))[5-2(1-t^(2))/(1+t^(2))])=0 The result functive and consequently the integral of this functive and consequently the integral of this functake.
