GeoGebra is free educational mathematics software that links dynamic geometry,
algebra and calculus.

Users can produce various constructions including...

points;

vectors;

segments;

lines; and

conic sections...

...as well as
functions, which can be altered dynamically
by mouse afterwards.

Direct input, e.g.
g:
3x + 4y = 7 or c: (x – 2)^{
2}
+ (y – 3)^{
2}
= 25, is also possible, and a range of commands, including
differentiation and integration,
are available for use.

Calculus

Adrian Banner, a lecturer at Princeton, has put together a lecture series (in video) that will help learners master calculus.

The 24 lectures were originally presented as review sessions for
Princeton introductory calculus courses offered in 2006, and each runs
about two hours.

Note: Adrian Banner has used these lectures to develop a book called The Calculus Lifesaver: All the Tools You Need to Excel at Calculus.
