Explain why or why not Determine whether the following statements are true and give an explanation or counterexample.
b. Euler’s method is used to compute exact values of the solution of an initial value problem. 

Verified step by step guidance

1. Recall that Euler's method is a numerical technique used to approximate solutions of initial value problems (IVPs) for differential equations, not to find exact solutions.
2. Understand that Euler's method works by taking small steps along the slope given by the differential equation, starting from the initial condition, to generate approximate values of the solution at discrete points.
3. Recognize that because Euler's method uses linear approximations over small intervals, the values it produces are approximations and generally contain some error compared to the exact solution.
4. Therefore, Euler's method does not compute exact values; instead, it provides an approximate solution that can be made more accurate by decreasing the step size.
5. Conclude that the statement 'Euler’s method is used to compute exact values of the solution of an initial value problem' is false, and the explanation is that Euler's method is inherently an approximation technique.

Key Concepts

Euler’s Method

Euler’s method is a numerical technique used to approximate solutions of initial value problems for ordinary differential equations. It uses tangent line approximations at discrete steps to estimate the solution curve, rather than finding an exact formula.

Initial Value Problem (IVP)

An initial value problem consists of a differential equation along with a specified value of the unknown function at a given point. The goal is to find a function that satisfies both the differential equation and the initial condition.

Exact vs. Approximate Solutions

Exact solutions satisfy the differential equation and initial conditions precisely, often expressed in closed-form formulas. Approximate solutions, like those from Euler’s method, provide numerical estimates that approach the exact solution as the step size decreases.
