Evaluate of each of the following integral:
Let us assume .....equation 1
By property, we know that
Thus
We know tan(– x) = – tan x
......equation 2
Adding equations 1 and equation 2, we get,
We know
Trigonometric identity sec2 ɵ
We know
Thus
We know
Thus
We know b and a being the upper and lower limits respectively.
Since
Thus
