Question
Transcribed Image Text:Solve the following equation numerically using the forward Euler method
du
=t2-10 with the initial condition u(0)=50
dt
As part of the solution process converge the solution by decreasing the step
size
You can determine the solution by taking the root-mean-square of the error
with respect to the exact solution. You will need to calculate the solution to
this differential equation. Then for each step size h, you can calculate the
root-mean-square of the error. Once the root-mean-square of the error is less
than the accuracy of the solution, your result is converged. Choose a time
grid say from 0 to 20.
Once you have this working, try solving using the Forward Euler method,
du
dt
=u*cos(t) with the initial condition u(0)=1, and using a mesh from [0,10].
