Foreword:

**Calculus
is an important tool and invention to look at some basic problems in Maths. Its
wide application has been influencing our lives through banking investments,
architecture,... Learning calculus is a must to understand our lives and the
world of advanced Maths. Many people around you may say ' we can use calculus
to solve this problem!', and you don't know the method to do so. For some
maximum and minimum problem, other than completing square (for quadratic
functions), AM-GM inequality (for some reducible fractions), calculus can solve
all optimum values for any functions. Another application is the finding of
volume of sphere, prisms,... Therefore, if you want to know more how the
formulae in your Maths books come from, calculus can be a tool to do so. Some
of the books uses very rigorous approach, and some of them claim to take you a
few hours to learn calculus... I won't criticize or doubt the effect of
learning through them, but I just want to help you learn the basic ideas of
calculus. Please click the links below to learn it step by step.**
