Question

cot11PI/3

Answer 1

Hi,

My name is Stephen. How are you, emms? Could you elaborate on your question, please.

Thank you.

Answer 2

its a homework question is says Find the value of cot 11 pi / 3 . ( answer to 3 demical places ) cot as in cos sin tan csc etc. can you help ?

Answer 3

First convert it into degrees, then find the angle it's equal to which is from 0 to 360 degrees.

Answer 4

ok,
thanks

Answer 5

If you don't know the unit circle, that helps a lot

Answer 6

cot11PI/3

cot(11) = pi/3 <-- correct?

Answer 7

cot(11pi/3)?

Answer 8

yes

Answer 9

Convert to a standard form. You could do this by subtracting \(2\pi\) again and again.

Answer 10

thanks i got my answer

Answer 11

You treat pi as 180 degrees, so 11pi/3 = (11*180)/3

Answer 12

*Or do the standard form thing :P

Answer 13

Kinda stops at \(5\pi/3\). Which is \(2 \pi - \pi/3 \).

Answer 14

OS seems to have broken itself. :(

Answer 15

Anyway, this thing is equal to\[\dfrac{\cos(2\pi-\pi/3 )}{\sin(2\pi-\pi/3)}\]

Answer 16

\[\cos(2\pi - x) = \cos(x)\]\[\sin(2\pi - x) = -\sin(x)\]

Answer 17

So... that'd be enough.

Answer 18

All emms is asking is the cot(300 degrees), I would think?

Answer 19

Yes. Which is equal to \(\cot(360 - 60)\).
