Anyone who works in the field of science
or is studying science will need to perform various calculations on a
daily basis. Just about every self-respecting scientist has a scientific
calculator of their choice or some type of applications that they
prefer, but these calculating devices are not always handy. For example,
sometimes you might have to do calculations when you are out of the
office or you simply don’t have these tools at your disposal.
In situations such as this, web
applications can come in really handy. Here is a list of five fantastic
web applications that provide access to great online scientific
calculators that all engineers, chemists, mathematicians and
statisticians can use on the go.
1. Google
Google is an excellent tool for
performing simple calculations. All you need to do is type the word
“calculator” in the search box. A calculator will appear, allowing you
to perform just about any calculation you need, including more
sophisticated functions like working with logarithms, trigonometric
functions and more.
2. Wolfram Alpha
If Google’s calculator is not advanced
enough for you, you should check out Wolphram Alpha, the knowledge
search engine. This tool is pretty amazing. Type in an equation and
you’ll get a solution immediately. Or just paste a function into the
search engine and you’ll be presented with its graphical representation,
properties and alternative definitions, all in a matter of seconds.
3. Eeweb calculator
Eeweb calcultor is a free tool developed
by and for the electrical engineering community. It is pretty simple to
use and will probably fulfill all of your calculating needs. In the
right-hand box, you’ll be presented with a list of all scientific
constants, which you can immediately use in your calculations. Also, you
can perform on-the-spot conversions between various metrics used for
length, speed, force, mass and much more. There is also an
equation-solver which is pretty intuitive and fast.
4. Web 2.0 calc
On first look, the Web 2.0 calc does not
look like it can do much, but check the bottom menu to see all of its
calculating powers. It is an excellent tool that enables you to
calculate a matrix, solve equations, and perform calculations with
fractions.
5. GraphCalculator
Graphcalculator is a pretty simple tool. It allows you to perform an analysis of functions in the coordinate system. Enter functions and they will be visually represented with the ability to calculate plot and intersection points as well.
