Staff Review
This lesson is an introduction to lines tangent to a curve at certain points. By finding the slope of these tangent lines, you are getting the idea of derivatives and instantaneous change for a curve. This is a good lesson leading up to derivatives. -

I was having difficulty with my homework until I saw this video. I had reviewed many other calculus sites, but this was the only one that helped me. -
