Question

t = 4π/3
(a) Find the reference number for the value of t.

Answer 1

\(\bf t=\cfrac{5\pi}{3}\qquad \pi \approx 3.1416 \qquad \implies \cfrac{5\cdot 3.1416}{3}\)

Answer 2

i tried that but it was wrong when i put it in

Answer 3

sounds pretty ambiguous... can you post a screenshot of the material?

Answer 5

do you have a Unit Circle?

Answer 6

for this question?

Answer 7

thats all there is to this question

Answer 8

for any whatsoever.... you should, is handy for getting known angles well, many online http://mathref.weebly.com/uploads/7/6/5/6/7656473/3491886_orig.jpg

Answer 9

notice where \(\bf \cfrac{4\pi}{3}\) is, the reference angle is the angle it'd make with the x-axis

Answer 10

i know that. its just that every answer i put in is wrong

Answer 11

wait nvm i got the answer. i just used the wrong pi symbol

Answer 12

you use the angle the terminal point makes with the x-axis, and then "REFERENCE IT" to the 1st Quadrant
