Question

How do you graph `y=-cscx`?

Answer 1

Draw `y=cscx`, then flip flop the graph around the x-axis

Explanation:

Let's start with the graph of `y=cscx`:

graph{cscx [-6.30, 3.6.30, -10, 10]}

The scale of the graph is set to run from `-2pi` to `2pi`. The asymptotes are at `npi` (where n is an integer), `y=1` at `x=pi/2+-n2pi` and `y=-1` at `x=(3pi)/2+-n2pi`.

With the addition of the negative sign, we'll be making positive y values negative and negative ones positive, so in essence we'll flip-flop the graph around the x-axis:

graph{-cscx [-6.30, 3.6.30, -10, 10]}
