Applications of Derivatives
Applications of derivatives: rate of change of bodies, increasing/decreasing functions, tangents and
normals, use of derivatives in approximation, maxima and minima (first derivative test motivated
geometrically and second derivative test given as a provable tool). Simple problems (that illustrate
basic principles and understanding of the subject as well as real-life situations).
