Question

fill in the cosine and sine values for all the given angles. show work for each of the calculations.

Answer 1

this is very easy :) to do

its just 1, 2, 3 then 3, 2, 1 divide each number by 2 and take the square root on the top

Answer 2

for both sides of the circle

Answer 3

each degree?

Answer 4

so all i have to do is write whats outside the circle?

Answer 5

yes

Answer 6

yes, first coordinate is cosine, second coordinate is sine

Answer 7

and if you can count to 3 you shouldn't have a problem

cos = x
sin = y

Answer 8

and remember to divide by 2 and take the square root of the top

Answer 9

soooo like 60 degrees divided by 2 then square root?

Answer 10

60 degrees is
\[\frac{\sqrt{1}}{2}, \frac{\sqrt{3}}{2}\]

Answer 11

45 degrees is just

\[\frac{\sqrt{2}}{2}, \frac{\sqrt{2}}{2}\]

30 degrees is just

\[\frac{\sqrt{3}}{2},\frac{\sqrt{1}}{2}\]

Answer 12

you should see a pattern, for the bottom part it is the same thing only arranged the other way around

Answer 13

I just memorized the unit circle got me through all my highschool courses and calc 1 without much studying

Answer 14

although satellites pdf file probably works just as well

Answer 15

thank you for your help..ill let you know if i have any other questions

Answer 16

there is a pattern in the radians of the circle

going counter clockwise, and remember the first quadrant
Reading from:
->2, 3 5
4, 5 7 <-
->5 7 11

those are all the numbers for each quadrants radians in order

Answer 17

ok.. thank you! :)
