Question

Some stupid trig questions, sorry.
Pardon me if I didn't notice the obvious answers to this xD I'm really tired!

1. Which trigonometric functions have a defined amplitude?
2. Which trigonometric functions have asymptotes?
3. Which trigonometric functions have a period of 2π?

Answer 1

Everything you need for these questions is here: The properties of the 6 trigonometric functions: sin (x), cos (x), tan(x), cot (x), sec (x) and csc (x) are discussed.

These include the graph, domain, range, asymptotes (if any), symmetry, x and y intercepts and maximum and minimum points.

Answer 2

Alright thanks! @Directrix :)

Answer 3

To help you get started:

1. Which trigonometric functions have a defined amplitude?

Sine and Cosine

Answer 4

Look at the link and see which ones have asymptotes. Look at the graphs.

Answer 5

Okay

Answer 6

Oh wait you answered that lol
My bad! ^^;

Answer 7

If you are on #2, then..
No. They are the only two that do NOT have asymptotes.

Answer 8

wow this glitch deleted my responses

"Sine and cosine?" referring to #1

Answer 9

Sorry. I will look at the page regarding #2 now

Answer 10

#1 is correct

Answer 11

#2: Everything BUT sine and cosine? Haha

Answer 12

Cosecant, Secant, Tangent, and Cotangent graphs have asymptotes.

Answer 13

Yes. :)

Answer 14

What about number 3?

Answer 15

Hmm, I'd say sine, cosine and tangent?

Answer 16

You are guessing.

Sine, Cosine, and two more.

The "two more" are the reciprocals of the sine and the cosine (if that helps.)

Answer 17

Oh, right ^^;
Eh... cosecant, secant.

Answer 18

... Not sure how though.

Answer 19

Correct.

Sine, Cosine, Cosecant, Secant.

Answer 20

I am confused... how? D:

Answer 21

Confused about what

Answer 22

sin + cos, yes I see, not sec and csc

Answer 23

3. Which trigonometric functions have a period of 2π?

There are 4 answers to this question.

Answer 24

>>Sine, Cosine, Cosecant, Secant.

Answer 25

Yes, but I do not see how Cosecant and Secant are within the boundaries of that categorization o_o

Answer 26

>>sin + cos, yes I see, not sec and csc

Don't use + for the word and. It will cause problems.

Answer 27

How did you see Sine and Cosine within the boundaries?

Answer 28

Eh....

Answer 30

You look for one cycle of the graph and then look across the x axis to get the period.

It will not always start with 0 and end in 2 pi. But, the difference between start and stop of one cycle will be 2 pi.

Answer 31

Oh, okay

Answer 32

Study the info at the link.

Answer 33

Alright.
