trigonometric graph transformations.
Hello,

$y = \frac{1}{3} sin \theta$ for this function would I multiply all the y values by 1/3 ?

Yes(Nod) all values of y for thetas of graph of equation

$y = sin \theta$

example for cos

An example of y = 10sin(x)

what about the graph of $y = sin \frac{1}{3} \theta$ ? Do I multiply all the x values by 3 ?

so 90 degrees times 3 etc....?

Here is another example for 4sin(x/3)
