Question

domain of y=tan(8x) in mathematical notation?

Answer 1

Can you do it in non-math notation?

Answer 2

I don't know how to do it either way.

Answer 3

OK, what numbers *can't* you put in for 8x?

Answer 4

I know I'm supposed to use pi and that's all I really know.

Answer 5

Where does tan() have asymptotes?

Answer 6

pi/2?

Answer 7

Yes! Every pi/2. So where does tan(8x) [note the 8x] have asymptotes?

Answer 8

Oh! so the domain should be like, can't = pi/2, and so on?

Answer 9

I think...

Answer 10

The domain of tan(x) excludes all pi/2 plus all multiplies of 2pi, and also -pi/2 plus all multiples of 2pi. But this is tan(8x)

Answer 11

so it should just be can't = 8pi/2?

Answer 12

Afraid not. It's where 8x = pi/2 + 2*pi*n or 8x=-pi/2+2*pi*n

Answer 13

I have no clue

Answer 14

well, try dividing what I typed for 8x by 8 to get x=(something) or x=(something else)
