With differentiation, one of the major concepts of calculus. Integration involves the calculation of an integral, which is useful to find many quantities such as areas, volumes, and displacement.
Decide whether you can find each integral using the formulas and techniques you have studied so far. Explain. (a) ∫2dx / √(x2 + 4) (b) ∫dx/x√(x2 − 9)
Let f(x) = 3× + 3, x, = 2, x2
and Ax = 1

(a) Find f(x) Ax
b) The sum in part (a) approximates a definite integral using rectangles. The height of each rectangle is given by the value of the function at the left endpoint. Write the definite integral that the sum approximates.

(a) Ef(x) Ax:
i= 1
(Simplify your answer.)
(b) Find the definite integral that is approximated by the sum in part a.
