Question:

The area under the graph of y = 1/1 + x2 and above the x-axis between x = a and x = b is given by

tan-1 b – tan-1 a


See figure

 1.5 -3 3


(a) Find the exact area under the graph of y = 1/1 + x2 and above the x-axis between x = 0 and x = √3.

(b) Find the exact area under the graph of y = 1/1 + x2 and above the x-axis between x = -√3/3 and x = 1.
