whats the rule for this....

were to put in a numerical value for t, for example t = 2.

First you'd find t + 1 = 2 + 1 = 3,

and t + 3 = 2 + 3 = 5,

and finally you'd divide 3 by 5 to get 3/5. The _last_ step in such a

calculation tells you the _first_ step in differentiating. In this

example the last step was a division, so begin the differentiation by

using the quotient rule.
