Evaluate of each of the following integral:
.
Let us assume .......equation 1
By property, we know that
Thus
.....equation 2
Adding the equations 1 and 2, we get,
We know
Trigonometric formula
We know
Thus
We know
Thus
we know b and a being the upper and lower limit
Since sinπ = 0 and sin (– ɵ) = – sinɵ
Thus
