p.17 Euler’s Method Example 2: Let us consider a particle of mass m that is in free fall towards the center of a planet of mass M. Let us assume that the atmosphere exerts a force Fdrag = Dv2 (22) onto the particle which is proportional to the square of the velocity. Here, D is the drag coefficient. Note that the x-axis is pointing away from ...

Euler's method is useful because differential equations appear frequently in physics, chemistry, and economics, but usually cannot be solved explicitly, requiring their solutions to be approximated. For example, Euler's method can be used to approximate the path of an object falling through a viscous fluid, the rate of a reaction over time, the flow of traffic on a busy road, to name a few.

Euler's method starting at x equals zero with the a step size of one gives the approximation that g of two is approximately 4.5. Find the value of k. So once again, this is saying hey, look, we're gonna start with this initial condition when x is equal to zero, y is equal to k, we're going to use Euler's method with a step size of one.

The formulas defining the method are based on some sort of approximation. Errors due to the inaccuracy of the approximation are called ...
