Euler's method for a first order IVP $y' = f(x, y)$, $y(x_0) = y_0$ is the the following algorithm. From $(x_0, y_0)$ we define a sequence of approximations to the solution of the differential equation so that at the nth stage, we have $x_n = x_{n-1} + h$, $y_n = y_{n-1} + h \cdot f(x_{n-1}, y_{n-1})$. In this exercise we consider the IVP $y' = e^x y$ with $y(0.5) = 2$. This equation is first order with exact solution $y = ln(e^x - e^{0.5} + e^2)$. Use Euler's method with $h = 0.5$ to complete the following table: In the first two rows enter the values of $x_n$ and $y_n$ and in the third row use the exact solution to find the errors $e_n = |y(x_n) - y_n|$. A calculator or other scientific software would be handy to work these types of problem. n 0 1 2 3 4 $x_n$ 0.5 $y_n$ 2 $e_n$ 0
