Question

Use a graph to solve the equation on the interval
[−2π, 2π].
(List the solutions in increasing order from left to right on the x-axis.)
csc x = −2

Answer 1

Are you using a graphing calc. or sketching it yourself?

Answer 2

Well, sketching it.

Answer 3

it's 1/sinx you can sketch it from the plot of that pretty easily:

Answer 4

if sinx is 1 cscx is 1; if sinx is zero cscx is +/- infinity; if sinx is negative so is cscx:
