Eulers on Tinspire CAS

[TheRajinator]

Hey I just found a function on the Cas cx that allows you to approximate using the eulers method. It is typed as euler() on the calc page. Wondering how to use it, I still can't figure it out. For a simple example: y'=3x^2 where y(1)=1, evaluate y(2) when step size h=0.5. If any one knows how to use this function help will be appreciated.
