Secant Approximations

point of tangency
h
tangent slope = 24
secant slope = 19.25
The most fundamental approximation in calculus is the approximation of the tangent line by a secant linethis is the approximation that leads to the derivative. Use the sliders to change the point of tangency and the point through which the approximating secant is drawn.
