Question

Evaluate integration of 1/(1+x^2) from 0 to 1 using Trapezoidal rule taking h=1/4.

Answer 1

Attempt :
h=1/4
therefore n=4
so according to the formula,
\[\LARGE I = h [ \frac{y_0 + y_4}{2} + 2(y_1+y_2+y_3)]\]
which turns out to be
\[\Large I = \frac{1}{4}(\frac{1}{2}. \frac{18}{17} + 0.5 + 0.2 + 0.1)\]
but gives wrong answer.
