## Question:

Consider the different equation {eq}\frac {dy}{dt}=t^3,y(0)=0. {/eq}

a) use elder's method with step size {eq}\Delta t=0.1 {/eq} to approximate {eq}y(0.4) {/eq}

b) what issue the exact value of {eq}y(0.4) {/eq}

## Numerical Solution of Ordinary Differential Equation (ODE)

The question presents a first-order, ordinary differential equation (ODE) with initial condition (IC) that comprises an initial value problem (IVP). Using the numerical Euler's Method we approximate a solution of the IVP at a point in the unknown's domain. The Euler's Method uses a fixed value of the step size {eq}\Delta t. {/eq} Next we use the separation of variables method to find the exact solution of the IVP and compare the exact value to the approximate numerical value from the Euler's Method above. Other concepts used in this question include regular integration from Calculus.
