WebThe idea of the method is as follows: one starts with an initial guess which is reasonably close to the true root, then the function is approximated by its tangent line (which can be computed using the tools of calculus), and one computes the x-intercept of this tangent line (which is easily done with elementary algebra). WebOct 13, 2024 · I am new to MatLab and I have to create a code for Euler's method, Improved Euler's Method and Runge Kutta with the problem ut=cos (pit)+u (t) with the initial condition u (0)=3 with the time up to 2.0.
