Question

Suppose that we use Euler's method to approximate the solution to the differential equation dy/dx = x^1/y; y(0.3) = 2. Let f(x, y) = x^1/y. We let x_0 = 0.3 and y_0 = 2 and pick a step size h = 0.2. Euler's method is the the following algorithm. From x_n and y_n, our approximations to the solution of the differential equation at the nth stage, we find the next stage by computing x_{n+1} = x_n + h, y_{n+1} = y_n + h * f(x_n, y_n). Complete the following table. Your answers should be accurate to at least seven decimal places. n x_n y_n 0 0.3 2 1 2 3 4 5 The exact solution can also be found using separation of variables. It is y(x) = Thus the actual value of the function at the point x = 1.3 y(1.3) =

00:01 Hello everyone, so let us take x0 y0 is equal to 23 and x1 y1 is equal to 2 .4 3 .3.
00:13 Now h x is equal to fx whole square.
00:20 Therefore, h0 y0 is equal to 23 and x1y1 is equal to 2 .4 3 .4.
00:31 So, slope of tangent 3 .3 minus 3 by 2 .4 minus 2 is equal to 0 .3 by 0 .4, that is equal to 0 .7...
