10.2#13, derivative of parametric equations

[@gmedran3]

10.5 and 10.6 are sections that I struggle most with in Ch. 10.. hopefully you go through every section in ch.10.

Factor e^(-t) and simplify before taking second derivative

I don't get the formula for the 2nd derivative ... I'll have to watch more videos on this topic :)
