I'm trying to write differential equations into R code. Can anyone help me
with the following equation:
(dy/dt) = v
(dv/dt) = y - y^3 + c(sin t)
where c is a constant. I've been using the "deriv()" function and
it seems to work out the best, but I'm having trouble converting the above
formula to R code.
Thank you,
Tim Sharac
