25 07 14 - Filed in: Markdown
Calca is a powerful symbolic calculator that updates as you type giving you instant answers. It solves equations and simplifies complex expressions. It's also a rich Markdown text editor so that you can explain your ideas alongside your calculations. This looks like a really interesting application,
Calculation Features:
- Variables
x = 42
- Functions
f(c) = 9/5*c + 32
and even recursive functions - Units 42 mph in kmph and currency ¥599 in $
- Solves equations (
x + 2x + 4x = 42
, what is x?) - Matrices with inverses so you can solve linear equations
- Sum, prod, map, and reduce operations on lists, matrices, and ranges
- Trigonometry and complex numbers
- Derivatives of functions
- Logic operations and if statements
- Binary math (& and |) and support for binary and hex number (
0xA9
and0b1010
) - Keeps track of units (m, s, m/s, m/s^2, etc.) so you can verify your equations as you compute
There is a comprehensive reference page that gives more details.
There is a MacOSX version and an iOS version for your iPad or iPhone.
The nice thing is you can use Markdown to format the calculation and add an explanation.
There is a listing of Markdown Editors for Mac OSX here,
