The Simple Pendulum

(continued from last page...)

After a fairly long think, Mathematica should have returned:

actsol=NDSolve[{y''[t]+9.8 Sin[y[t]]==0, y[0]==y0, y'[0]==v0},y[t],{t,0,15}]

Actual Solution

Now do the [[1,1,2]] trick again, this time on actsol. (I'm not going to give you the command this time--good grief, you've seen it enough times by now.)

Go on, get to work!

Moving on...
