The derivative is a basic concept of differential calculus. However, if we calculate the derivative as change in distance over change in time, the result at any instant is 0/0, which seems meaningless ...

Check your understanding of differential calculus and practise finding the greatest/least value(s) a function can take using optimisation. Create an expression for and use optimisation to find the ...

THIS book seems well adapted to serve as a text-book for a first course in the differential and integral calculus. Fourteen chapters deal with the differential calculus and its applications to maxima ...
