Ok, so think of theta as a variable

if theta was an 'x' how would you solve?

2 cos theta=1 cos theta=1/2 theta=cos inverse(1/2) theta=60degrees

Now, you know cos theta equals 1/2..now you want to find theta, do you know how?

oh! okay and would I just look for cos (x) value on the unit circle right?
 one year ago

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.1
Umm, you could do that. But im not sure if you would have the unit circle with you on your tests.

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.1
There is another way to do it, if you have a graphing calc or if you memorized the cos and sin values of the major degrees on the circle.

well no lol my precal teacher was trying to explain how to but I couldn't understand
 one year ago

amhishaw Group TitleBest ResponseYou've already chosen the best response.0
without it*

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.1
Ohh, ok. Well try to memorize the major degrees..like 30, 60, 45, 90, 180, 270, 360.

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.1
But if you were to use your unit circle, you would look for the degrees with a cos (x value) of 1/2

ok, so would i use ALL of the radian values of cos 1/2?
 one year ago

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.1
do you know the cos and sin values of the angles I drew?
 one year ago

Brittni0605 Group TitleBest ResponseYou've already chosen the best response.1
Yes, all of the values, bc the problem says find ALL
 one year ago

amhishaw Group TitleBest ResponseYou've already chosen the best response.0
I know most of them

thank you so much, you've been a lot of help
