A question in Thomas Lee's book

In 2nd edition, chapter 15, page 498
It is said if there is a current i_d = i_rf×sin(ωt) for i_d > 0
the "fundamental component" of i_d is equal to
(2/T)×∫i_rf×sin(ωt)sin(ωt)dt from 0 to (T/2)
I know it's a little difficult to understand my equation.
What I want to ask is why finding a fundamental component
is equal to multiplying the signal by a sine wave then integrate?
Plz help!

Hi
You should check out some books about Fourier Series.
Regards
you need not pay much attantion about that.
