Basic Related Rates Problems

When it comes to related rates, there aren't really any "basic" ones; this is the hardest topic in derivatives. But these problems are at least pretty straightforward: if you need to use the area formula for a circle, the words "area" and "circle" are going to be in the problem. That might not sound like much, but it's a lot more of a hint than they'll give you in the hard ones of the later videos.
