The purpose of this paper was to propose an improved approximation technique for the computation of the numerical solutions of initial value problems (IVP). The actual solution can barely be seen and the numerical solution gets out of control very quickly this solution is completely useless the scales on the $y$-axis are enormous and increasing the step-length only makes this worse. These methods axe derived by approximating the Euler equations via linearization and diagonalization. The simplest possible integration scheme for the initial-value problem is as follows. Solving this equation is daunting when it comes to manual calculation. What are the advantages and disadvantages between the Euler and Lagrange approach? 5. The amount of input students absorb . The basic idea behind the formation of this method is to find the approximate values for the differential problems. . D'Alembert's principle may be stated by . After that insert the form in the differential equation & simplify the resulting equation for the constant. In order to describe the fluid motion by Eluerian method, a flow domain of definite volume or control volume will be defined through which fluid will flow in and out of control volume.

In the improved Euler method, it starts from the initial value(x0,y0), it is required to find an initial estimate ofy1by using the formula. It only takes a minute to sign up. Let's denote the time at the nth time-step by t n and the computed solution at the nth time-step by y n, i.e., .The step size h (assumed to be constant for the sake of simplicity) is then given by h = t n - t n-1.Given (t n, y n), the forward Euler method (FE . The research design can be very complex; discrepancies can be unclear and hard to be corrected. In this project, I must compare THE Runge-Kutta method (4th order) with Euler to explore the advantages and disadvantages. =Fb#^{.idvlaYC-? This method takes twice the number of function evaluations than Euler's method, though it gives more accurate results it takes more time of execution. It is said to be the most explicit method for solving the numerical integration of ordinary differential equations. Letting \(\rho=1/2\) in Equation \ref{eq:3.2.13} yields the improved Euler method Equation \ref{eq:3.2.4}. Approximation error is proportional to the step size h. Hence, good approximation is obtained with a very small h. Find Math textbook solutions? . Findings may be difficult to be interpreted. Therefore the local truncation error will be larger where \(|y'''|\) is large, or smaller where \(|y'''|\) is small. Genetically modified foods promise to meet this need in a number of ways: We begin by approximating the integral curve of Equation \ref{eq:3.2.1} at \((x_i,y(x_i))\) by the line through \((x_i,y(x_i))\) with slope, \[m_i=\sigma y'(x_i)+\rho y'(x_i+\theta h), \nonumber \], where \(\sigma\), \(\rho\), and \(\theta\) are constants that we will soon specify; however, we insist at the outset that \(0<\theta\le 1\), so that, \[x_i
