To limit the domain or range (x or y values of a graph), you can add the restriction to the end of your equation in curly brackets {}. For example, y=2x{x>0} would graph the line y=2x for x values greater than 0.

To try it out in Desmos, click the Restrictions Tour in the help menu:

that is very helpful, can you show us how to do a step peicewise?

More:

- you can cumulate conditions: y = sin ( x/a ) { a > 0 } { 0 <= x <= a*pi }

- for parametrics curve, the condition must be *in* the parenthesis: ( t, sin ( t/a ) { a > 0 } )

- you can also use the "if elseif else" version : y = { a <= 0 : 0 , 0 <= x <= a*pi : sin ( x/a ) , 0 )

with any number of cond : expression terms, and the default (final) expression is not mandatory
