Question

What is the period of f(x) = - tan 4x?

Answer 1

@Pssssst Do you know the period of tan x?

Answer 2

No, I do not.

Answer 3

Ok, do you know what does period mean ?

Answer 4

For a function

Answer 5

Honestly, no.

Answer 6

OK, I'll explain :)

Answer 7

Thank you, and sorry haha. :)

Answer 8

Let a function be f(x), T is it's period if
\[f(x+T)=f(x)\]
it'll also hold for integral multiples of T
\[f(x+nT)=f(x)\]
n=1, 2, 3,4, 0, -1, -2

Answer 9

If you look at the graph of tan x, it's period is \(2\pi\)

Answer 10

Do you get this?

Answer 11

Alright. I'm following.

Answer 12

Now if we have tan 2x, it's period will be \(\frac{2\pi}{2}\)
can you tell me, what will be the period of tan 4x ?

Answer 13

@Pssssst ??

Answer 14

I'm sorry, I had to do something. hah

Answer 15

4x/2

Answer 16

My bad, * 4x/4 right?

Answer 17

Read carefully at my posts again :)

Answer 18

The period of tan 2x is 2(pi)/2? or 2x/2? It's hard to read it on my computer
