Improved euler's method formula
Witryna10 maj 2024 · Hi so I have a problem from my differential equations class that I am having difficulty solving with the improved Euler's method: The logistic equation for the population (in thousands) of a certain species is given by dP/dt = 2P-2P^2. With t being time variable in years. Given P(0) = .5, with step size h = .2 (so .2 of t), find population … Witryna6 sty 2024 · Use the improved Euler method with step sizes h = 0.1, h = 0.05, and h = 0.025 to find approximate values of the solution of the initial value problem y ′ + 3y = 7e4x, y(0) = 2 at x = 0, 0.1, 0.2, 0.3, …, 1.0. Compare these approximate values with the values of the exact solution y = e4x + e − 3x, which can be obtained by the method of …
