Que. 5 Show that the average value of sin2 ? over [0, 2π] is equal to 1/2 Without
further calculation, determine whether the average value of sin2 ? over [0, π] is also
equal to 1/2.
Answer:
We know that,
sin2 ? + cos2 ? = 1
Taking Average both sides,
???(sin2 ?) + ???(cos2 ?) = 1
Also average of sin2 ? and cos2 ? has same value over [0,2?].
So,
2???(sin2 ?) = 1
???(sin2 ?) =
