Question

i want to graph 3csc2x but I dont know how!! can someone help me with steps!??

Answer 1

do u knw the graph of cosec x?

Answer 2

One way might be to try rewriting 3csc(2x) as 3/sin(2x).

Then from here, mark on your graph where one period should end and where the amplitude should be. Since it's 1/sin it will be "upside down"

Look at this picture to give yourself some help along the way so that next time you can see.

The main points to hit when graphing any trig function are what it looks like at 0, T/4, T/2, 3T/2, and T, since it repeats after that and you can kind of "guess" by filling in the points between where the curve should look like.

Answer 3

i know that cscx = 1/sinx

Answer 4

so if i put that function... 3/sin(2x)?

Answer 5

i can help with an alternate solution ..but for that you need to answer my queries

Answer 6

the graph of csc ..yes i do know what it is!

Answer 7

Find the amplitude and period.

Answer 8

well thats great...now what you need to understand is that the graph of cosec 2x will be same as cosec x only difference is that we have to minimize the graph to t=pi

Answer 9

let me show u how i do that for sin 2x
