== The Console Tab ==
<!--T:16-->
When you first open '''KAlgebra''' a blank window shows up, this is the main work area for calculus.
* [https://docs.kde.org/stable/en/kdeedu/kalgebra/index.html The KAlgebra Handbook]


Let's get started with a little example of how '''KAlgebra''' works, just type:
<!--T:21-->
{{Input|1=2+2}}
* [http://swiftscythe.blogspot.com/2011/02/how-to-work-with-complex-numbers-in.html How to work with complex numbers in KAlgebra]
Then type <keycap>Return</keycap> and '''KAlgebra''' will show you the result. So far it's easy.


However, '''KAlgebra''' is much more powerful than that, it started as a simple calculator, but now it's almost a CAS.
==Other== <!--T:17-->  
You can define variables this way:
{{Input|1=k:=3 }}
And use them normally:
{{Input|1=k*4}}
And that will give you the result: 12
You can also define functions:
{{Input|1=f:=x->x^2}}
And then use them:
{{Input|1=f(3)}}
Which should return 9.
You can define a function with as many variables as you want:
{{Input|1=g:=(x,y)->x*y}}
The possibilities of defining functions are endless if you combine this with the piecewise. Let's define the factor function:
{{Input|1=fact:=n->piecewise { n=0 ? 1, n=1 ? 1, ? n*fact(n-1) } }}
Yes! '''KAlgebra''' supports recursive functions. Give some values to n, to test it.
{{Input|fact(5)
fact(3)}}


'''KAlgebra''' has recently started support for symbolic operations, to check it out, just type:
<!--T:18-->
{{Input|1=x+x+x+x}}
* [[Special:myLanguage/KAlgebra/Homework|Homework]] is a page which show some uses of KAlgebra in real world.
or
{{Input|1=x*x}}
It doesn't work on some complex structures, though. Only basic support so far.


Moreover, '''KAlgebra''' has support for differentiation.
<!--T:19-->
An example of the syntax:
* [http://edu.kde.org/applications/school/kalgebra/ The Project Page] contains further helpful links, including links needed for bug reporting or contacting the authors. Here you will find information about mailing lists and the IRC channel.
{{Input|1=diff(x^2:x)}}


If you have used '''KAlgebra''', you will have noticed the syntax completion support, which is very helpful.


Another resource that can be useful to learn more about '''KAlgebra''' comes with '''KAlgebra''': The '''Dictionary''' tab. It contains examples of every function supported by '''KAlgebra'''. Maybe the best way to learn how to do things with '''KAlgebra'''.

KAlgebra is a calculator with symbolic and analysis features that lets you plot 2D and 3D functions as well as to easily calculate mathematical expressions.

It is part of the KDE Education Project.
