slope of tangent

Introduction

The derivative of a function of a single variable at a chosen input value, when it exists, is the slope of the tangent line to the graph of function at that point.

User Guideline -

1.Construct the polynomial f(x) = x^2/2 + 1, 2.Create new point A on function f(x), 3.Create tangent t on function through point A by input t=Tangent(A,f) in input bar, 4.Create slope of tangent by input m=Slope[t] in input bar, 5.Define point B by input B=(x(A).m) in input bar, 6.Join point A and B, 7.Trace on for point B, 8.To visualize derivative of slope of tangent,drag the point A.

Learning Objective:-

  • Students will be able to define the derivative of slope of tangent with example.
Dynamic Applet-

Test your Understanding-

When we drag the point then the slope of tangent is Dynamic ?

Select all that apply
  • A
  • B

Create dynamic applet on derivative of slope of tangent by using following protocol.

  1. Enter the polynomial f(x) = x^2/2 + 1,
  2. Create a new point A on function f. Hint: Move point A to check if it is really restricted to the
  3. function,
  4. Create tangent t to function f through point A. t=Tangent(A,f),
  5. Using Input Box,
  6. create slope of tangent t using: m = Slope[t],
  7. Define point B: B =(x(A), m) Hint: x(A) gives the x-coordinate of point A,
  8. Connect points A and B using a segment,
  9. Trace On for the point B,
  10. Perform the drag test to visualize the derivative as slope of tangent.
