Evaluate ∫1,0 1/(1+x^2) dx exactly and show that the result is pi/4. Then, find the approximate value of the integral using the trapezoidal rule with 4 subdivisions. Use the result to approximate the value of pi.
The approximate value of is:
Give your answer accurate to four decimal places.
"The approximate value of the integral using the trapezoidal rule with 4 subdivisions is 2.4142"
This statement is total nonsense, it should clearly be close to .78
