How do you graph y=-cscx?

1 Answer

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]}
