How to graph a function with respect to y on a TI-84

[lLovePhysics]

Homework Statement

I'm having difficulty graphing with respect to y (unless I graph it point by point).

For example, I find it hard to graph: $$f(y)= \frac{y}{\sqrt{16-y^2}}$$


Does anyone know of an easy method to graph such a function or know how to do it on a Ti 84+ SE? Also, it would be great if someone could link me to a website that shows you a method. Thanks!

Whenever you graph something, you need to first identify the independent and independent variables. In this case, y is the independent variable and f(y) is the independent variable so it is really no different than graphing an equation with x and f(x).

Most graphing calculators will only let you call the independent variable "x" and the independent variable "y" so this is a time when you just have to be smarter than the calculator.

Graph $$y= f(x)= \frac{x}{\sqrt{16-x^2}}$$
and then turn your calculator on its side!
