1. Consider the linear first order differential equations given below. Using forward Euler method, obtain the finite difference approximation. Find the amplification factor, and using the appropriate stability condition, find any constraints on the step size. Indicate if the forward Euler method is conditionally stable, unconditionally stable, or unconditionally unstable. Show all steps. \frac{dy}{dt} = -20y; \quad y(0) = 10. (1)

John Wallis was an English mathematician who lived between 1616 and 1703, he discovered the following approximation to $\pi$ which is commonly known as the Wallis Product. Write an octave command that will approximate pie ($\pi$) by only using 20 terms of the Wallis Product. (25) $\pi \approx 2 \prod_{n=1}^{20} \left(\frac{4n^2}{4n^2 - 1}\right) = \left(\frac{4(1)^2}{4(1)^2 - 1}\right)\left(\frac{4(2)^2}{4(2)^2 - 1}\right)\left(\frac{4(3)^2}{4(3)^2 - 1}\right) \dots \left(\frac{4(20)^2}{4(20)^2 - 1}\right)$
