Trapezoid Rule approximations Find the indicated Trapezoid Rule approximations to the following integrals.

using n = 2, 4, and 8 subintervals

Step 1:

By Trapezoidal rule we have to find the integral using 2,4,8 subintervals

Step 2:

Trapezoidal Rule

dx ≈

Where

Step 3:

Here y=f(x)=

(i) for n=2

For x=1 y=

x=5 y=

x=9 y=

Therefore

=
