Maxima And Minima
Gbogbo ọrọ náà
Differentiation finds the high and low points of a curve: where it stops rising and starts falling, or the reverse. This is the key to optimisation, finding the greatest area, the least cost, the maximum height.
In this lesson you will apply differentiation to find stationary points and to practical maxima and minima problems, using the first and second derivative tests to tell a maximum from a minimum.
Ebumnobi
- Apply differentiation to practical problems involving maxima and minima.
- Use the first and second derivative tests to distinguish between maxima and minima.
