The differential equations are: dxdt = @(x,t) -1.*y-0.1.*x; I am trying to implement both the explicit and implicit Euler methods to approximate a solution for the following ODE: dx/dt = -kx, where k = cos(2 pi t), and x(0) = 1. Euler's methods use finite differencing to approximate a derivative: dx/dt = (x(t+dt) - x(t)) / dt. The forward method explicitly calculates x(t+dt) based on a previous solution ...
