TITLE: Using EXP in equation
QUESTION [5 upvotes]: I have the following equation: 
$\ y' = te^{-2t} - 2y$
Where e is the exponential function. However when I see this being used I see EXP(x) and I don't understand how i'd write the equation with that terminology. So how would I rewrite this to use EXP(x)?

REPLY [8 votes]: $\mathrm{exp}(x)$ is just a different notation for $e^x$, so your equation would become $y^\prime = t\mathrm{exp}(-2t)-2y$.
