Answer 4

cotx = \[\frac{ cosx }{ sinx }\]

Answer 5

so whats the answer?

Answer 6

@savanna_18

Answer 7

A fraction will be undefined when the denominator is 0, so when sinx = 0, there will be an asymptote.

Answer 8

so its a?

Answer 9

When does sinx = 0?

Answer 10

sin 0 = 0
sin 180 = 0
sin 360 = 0
sin -180 = 0

Answer 11

okay so its b????

Answer 12

Why do you think it's b

Answer 13

so its b

Answer 14

Well anyway, if you notice, you add 180 degrees each time, which is pi.

Answer 15

okay so b is correct?

Answer 16

No, it's not b

Answer 17

what is it??????

Answer 18

oh so its D

Answer 19

You said:
sin 0 = 0
sin 180 = 0
sin 360 = 0
sin -180 = 0

Each time you add 180 degrees, or pi, so sin at every pi = 0.

Answer 20

right so d?

Answer 21

Yes d.

Answer 22

thank you.

Answer 23

No problem, I hope you understand the concept!
