Taking the derivative seems to be the easiest way of dealing with solving for instantaneous velocity. Should I ever bother with taking the reciprocal, simplifying, or factoring the expression in order to find the 0/0 culprit and cancel it out, or should I just take the derivative each and every time?
If so, why do we even bother learn these other long methods of finding the derivative where we can just use the derivative relatively simple rules to find it, and then we can find easily find the limit as x goes to 0, thereby finding our instantaneous velocity.
