The area (in square units) of the region enclosed by the two circles x2 + y2 = 1 and (x - 1)2 + y2 = 1 is
The values of a function f(x) at different values of x are as follows
x | 0 | 1 | 2 | 3 | 4 | 5 |
f(x) | 2 | 3 | 6 | 11 | 18 | 27 |
Then, the approximate area (in square units) bounded by the curve y = f(x) and x-axis between x = 0 and 5, using the Trapezoidal rule, is
