## Homework Statement

I am reading about related rates in my calc book but it doesn't really explain it very well. Are there any arcitcals some one can send me that goes indepth about this concept on related rates?

Thank you.

A typical problem goes something like this:

A plane is flying at a constant speed of 120 mph at a constant altitude of 10,000 ft away from an observer on the ground. At what rate is the observer's angle of elevation to the plane changing three minutes after the plane flies directly over the observer?

The first equation I referred to would be an equation that relates the angle of elevation ([itex]\theta[/itex]) and the horizontal distance (x) the plane has flown at an arbitrary time. The second equation (the related rates) would involve d[itex]\theta[/itex]/dt and dx/dt. You would solve for d[itex]\theta[/itex]/dt, and evaluate it at the indicated time.
