Question

Themean value of current I = locoswt from t =0 to t=π/w

actually I know how to do this question I just wanted to ask that we can write t=π/w as t=T/2 as w=2π/T so why the answer is zero when for half cycle the current is 2Inot/π
please address the asked doubt only...pls pls it's a request​
