Q1). For the function, do the following.
f(x) = 3/x from  a = 1  to  b =2.
(a) Approximate the area under the curve froma to b by calculating a Riemann sum using 10rectangles. Use the method described in Example 1 on page 351,rounding to three decimal places.
(b) Find the exact area under the curve from a tob by evaluating an appropriate definite integral using theFundamental Theorem.
