Gradient of a Curve

fx-CG50 A-Level IB

This investigation leads learners to use the calculator generated values for the gradient of curves at a selection of points to find a pattern and hence a formula for the gradient function. Learners collect several gradient functions to formulate the rule for differentiating powers of x. It by-passes first principles altogether so that learners are comfortable with differentiation before tackling first principles.
