Example1 (Velocity Calculator)
Distance[m] = x
Time[s] = t
Velocity[m/s] = x/t

Example2 (Desnity Calculator):
Mass[kg]=m
Volume[m3] =v
Density[kg/m3] =m/v

Example3 (Volume Calculator):
Length=x
Width=y
Height=z
Volume=x*y*z
BaseArea=x*y

Example4 (Trigenometric Calculator):
Degrees=d
@rad=d*(PI/180)
SIN=sin(rad)
COS=cos(rad)
TAN=tan(rad)

FAQs:
=====
* What is the "programmable custom formula Calculator"?
- It's an app that allows you to write your custom formula and convert it to custom calculator easily.


* How RubikCalc is different from any other programmable calculator?
- RubikCalc is totally different from other programmable calculator so that it's not a static app, it's totally dynamic, you can create your own customized formula calculators and save it and use it later.


* Can I use variables names like this p1,a3?
- No, you cannot mix numbers with letters in variable names, just use single symbols a,b,c,x,y,

* How does the app distinguishes between inputs and outputs?
- Outputs contains formula like this: Velocity=x/t,Square=x^2
While Inputs are just definitions like this: Distance=x, Time=t, Radius=r

* How can i specify units?
- Put the units between brackets after the name like this, Distance[m]=x

* How can i use the logarithmic function?
- Just write log(3),log(4).

* Can i use PI ?
- Yes, just write PI, all capital.
