Hello,
I have created two online calculators which (I hope ) can prove useful:

Derivative Calculator (with steps)
It can do first, second, third derivative (symbolic) with respect to any variable and optionally simplify input and output. The input formula is being displayed as a LaTeX formula while typing, in order to minimize input mistakes (such as writing 1/a+b when you really mean 1/(a+b)). This calculator can show the calculation steps.

Integral Calculator (no steps feature yet)
Same user interface as the above one, but it can do antiderivatives and definite integrals (also some improper ones).

The following site is good for 2D and 3D graphing:

Furthermore it can also calculate symbolical derivatives of the expressions and plots them at the same time:

The input window for the expressions is really handsome :-)

Check out Meta Graphing Calculator --written in HTML5, does implicit equations and produces point table. Also can do matrix mathematics and stats calculations like T-tests and regressions.
