Defining Variables
Syntax: beta=45
| Example | Syntax |
|---|---|
| beta := 45 | beta=45 |
| alpha := 2*beta | alpha=2*beta |
Define your own variables using =.
Note: Variables do not automatically change their value when defined using other variables. alpha in the example will keep its value (90) even when you change beta.
If you need a dynamic variable, use functions instead.
