Calculus AB/BC - Approximating a Function's Value Using Local Linearity

Curated and Reviewed by Lesson Planet

No need to be exact every time. Pupils watch an engaging video on approximating function values. They see how to write the equation of a tangent line, use it to calculate approximations, and then determine whether it is an overestimate or underestimate based on the function's concavity.
