Graphing Sin Functions: Calculator Tips and Tricks for y=sin(c(x-d))

[trivk96]

Homework Statement

This may seem like a stupid question so i apologize.

This is the general form for the said equation: y=sin c (x-d)

c= 28
d=3

How would i enter this into my calculator (ti 84) to graph it??

Homework Equations

The Attempt at a Solution

y=sin (28)(x-3)
or
y=sin (28(x-d))
or something else.

Again, I apologize if this is a stupid question

Depends on whether you mean y=(sin(c))*(x-d) or y=sin(c*(x-d)). I suspect the latter, but that's just guess. If they just said y=sin c (x-d) that's kind of ambiguous, as you noticed. It's not a stupid question, but there's no clear answer.
