As we learnt 

 

Properties of Definite Integration -

 

\int_{a}^{a+x\, T}f\left ( x \right )dx= x\int_{0}^{T}f\left ( x \right )dx

 

(Formula)

- wherein

If  f\left ( x \right ) is periodic with period T and x\in N

 

 = 4\int_{0}^{\pi}\tan x\: \: dx= 4\left [ \ln \left ( \sec x \right ) \right ]^{\pi}_{0}= 0
