Manipulating a Sine or Cosine Function
▶ To translate, grab near the axis of vertical symmetry of the graph, and then drag.
▶ To stretch, grab away from the axis of vertical symmetry of the graph, and then
drag.
Specifying a Function with Domain Restrictions
You can use the entry line or the Calculator application to specify a function with
domain restrictions. For multiple domain restrictions on a function, use the piecewise()
function.
In the following example, a function with a domain that is less than 2 and greater than
-2 is specified on the entry line:
1. From the GraphEntry/Edit menu, select Function.
