Question

5. (5 marks). In this question, we will investigate the error involved in using the Trapezoid Rule to approximate the integral $$int_{1}^{2} e^{1/x} dx$$ (a) How large do we have to choose n so that the approximation $T_n$ is accurate to within 0.0001? 0.00001? 0.0000001? Show all of your work. (b) Write some code (in any programming language) that can calculate the Trapezoid Rule approximation $T_n$ for various values of n. Your code should accept as an input the choice of n, but you may hard code the function $e^{1/x}$.

Step 1

First, we need to find the error bound for the Trapezoid Rule. The error bound for the Trapezoid Rule is given by: $$E_n \leq \frac{(b-a)^3}{12n^2} \cdot K$$ where $a$ and $b$ are the limits of integration, $n$ is the number of subintervals, and $K$ is the Show more…
