how to solve a second-order differential equation set with parameter using Euler's method?

i try the following, but then i find that i didn't clearify my "dy" is the derivative of time "t"

how can i limit the dy is the derivative of "t"?

my function is the following

thanks in advance!

Actually, dy is the derivative of y with respect to t. The code you give is absolutely right.

So you see Euler's Method

If you denote dy as dydt (), then it will be more obvious.
