Numerically solve an IVP
Produce and IVP of the form
y' = r\,y\,\sin(y), : y(0)=1
by choosing the decimals of $r$ to be the positions in the alphabet of your login name.
For example, my login name is
mark and the positions of those letters are 13, 1, 18, and 11. Thus, for me, $r=0.1311811$ and my ODE is
y' = 0.1311811 \, y \, \sin(y).
Find the value of $t$ for which $y(t)=3$.
