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.

GraphFree
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.

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.

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.
