When you replace s(a) and s(t) withand
, you get a lot of cancellation. Remember the identity
.
They're getting you ready for derivatives - the limit you are calculating is just the derivative of s(t) at a.

So s(a) and s(t) are the exact same? Why do they have different letters then?
No,and
. So when you plug them in, 200 cancels and you can factor out -4.9, giving
