i have an equation s = (t+1)/(t+3).

I want to differentiate it to get ds/dt ?


whats the rule for this.

Thanks

Here's a way to approach all questions like that. Suppose you
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.
