Euler's method is a numerical method for generating a table of values (xi , yi) that approximate the solution of the differential equation y' = f(x,y) with boundary condition y(xo) = yo. The first entry in the table is the starting point (xo , yo.). Given the entry (xi , yi ), then entry (xi+1 , yi+1) is obtained using the formula xi+1 = xi + x and yi+1 = yi + xf(xi , yi ). Where h is the small value called step size. Use Euler's method to estimate the value of y when x = 2.5 for the solution of the differential equation y' = x + 3y/x with the boundary condition y(1) = 1. Take x = 0.1, the exact solution of this differential equation is y = 2x3- x2. Compare your approximation values with the exact value.

dont ans this question
Euler's method is based on the fact that the tangent line gives a good local approximation for the function. But why restrict ourselves to linear approximants when higher degree polynomial approximants are available? For example, we can use the Taylor polynomial of degree about = No, which is defined by P.(x) = y(x) + y (xo)(x – Xa) + 21 (x- This polynomial is the nth partial sum of the Taylor series representation (te) (x –...
