The exact value is
I would hope you get negative values! What's your h?
I am revising the trapezium rule and I can't continue because I am stuck on an exercise question.
I am asked to find the approximation for this value using the trapezium rule between x = 1 and x = 4
When I work it out I keep getting a negative value. What would I do here.
Here's a detailed calculation of the exact integral using the Fundamental Theorem of the Calculus:
as mentioned before.
Using the trapezoidal rule, I believe you will have
I get -4.375, which isn't too awful bad, compared with the true value of -4.5.
