Differentiating at a Point
- Daniel Fishman
Move the point labeled "A" and the slider labeled "dx"
1) Describe how B and C are determined from A and dx 2) Notice how the line disappears when dx=0. Why does it disappear? 3) How would you come up with an estimate for the slope of the tangent line to the curve y=f(x) at the point where x=0?
