ASCIIMath Scientific Calculator

Javascript, MathML, MathPlayer
Smart Math Calculator

Computes multiple math expressions simultaneously. High precision with support for 1000+ digits accuracy. Results are calculated instantly as soon as you type them. Define your own variables and functions. Solve equations for unknown variable x.

Its beautiful user-interface is designed for efficiency. Previous sessions are automatically saved and you have the option of always keeping the calculator in memory or on top of other windows. Downloador try online.
Uncertainty Calculator (javascript)

This is a device for performing calculations involving quantities
with known or estimated uncertainties. This is known as error
propagation or uncertainty propogation.
It calculates uncertainties two ways:

most probable uncertainty, also called standard error
(or uncorrelated uncertainty), which is used when errors are independent;

maximum uncertainty, also called maximum error
(or correlated uncertainty), which is used when they are not.

Statistical calculator (javascript)

This calculator can do basic statistical analysis of a set
of repeated measurements, including measurements with uncertainties.

Derivative Calculator (javascript)

An online symbolic derivative calculator that lets you compute derivatives
and partial derivatives of arbitrary mathematical functions.
Integral Calculator (javascript)

An online calculator that supports definite integrals as well as
indefinite integrals (antiderivatives). Works for complex functions as well.

Graphing Calculators

CLIPS Calculator - Graphing mode

an implementation of the function graphing tools by Kaskosz and Ensley
Desmos Graphing Calculator
a very nice Flash-based implementation
This free online graphing utility can plot a wide variety of functions including polar, parametric, piecewise, conics (and other implicit plots), and even slope fields. You can plot up to six functions at once, mixing and matching function types. Other features include the ability to shade inequalities or the area between curves, several different grid types (cartesian, polar, semi-logarithmic, and number line), and the ability to add legends and/or captions.

GraphApplet 1.05
implemented at Cool Math Graphing Calculator
7 Stones Graphing Calculator
Graphical Function Explorer (GFE)
GFE is a free web-based function graphing tool that allows you to plot up to three functions on the same set of axes. In the functions you can refer to up to four independent variables that are controlled by sliders. This allows you to easily see the effect of changes since the graphs change in real time as you drag the sliders.

Time Value of Money Calculator
Bank of Canada Inflation Calculator
The Inflation Calculator uses monthly consumer price index (CPI)
data from 1914 to the present to show changes in the cost of a fixed
"basket" of consumer purchases.
These include food, shelter, furniture, clothing, transportation, and recreation.
An increase in this cost is called inflation.
