Question

Find the sin,cos, tan of the follwing angle
pi/6

Answer 1

use this unit circle
http://etc.usf.edu/clipart/43200/43215/unit-circle7_43215_lg.gif

locate the angle pi/6
then mark the corresponding point to this angle
the x coordinate of this point is equal to `cos(pi/6)`
the y coordinate of this point is equal to `sin(pi/6)`
divide `sin(pi/6)` over `cos(pi/6)` to get `tan(pi/6)`

Answer 2

do i get 3 answer?

Answer 3

yes you'll have 3 different results for sine, cosine, tangent

Answer 4

DO i write the answer in degree or fraction?

Answer 5

they'll be fractions with square roots in them

Answer 6

well except for sin(pi/6)

Answer 7

can u show me the exampple of the answer im confused what should i write

Answer 8

see attached

Answer 9

let me know if that helps or not

Answer 10

but do i have to write 3 answer?

Answer 11

do you see how I got \[\Large \cos\left(\frac{\pi}{6}\right) = \frac{\sqrt{3}}{2}\] ??

Answer 12

yes

Answer 13

im so confuse

Answer 14

whats the y coordinate of that point

Answer 15

is the answer just radical 3/2

Answer 16

that's for cos(pi/6)

Answer 17

what bout sin or tan
