  1. Wait patiently for a helper to come along.
  2. Once someone helps you, say thank you and close the thread with:
+close
  1. Feel free to nominate the person for helper of the week in #helper-nominations

well just solve for cos(x) but idk how they expect you to use the unit circle because this is not a unit circle angle

#

and you can remember that cos is the horizontal coordinate so you will get 2 values of cos(x) and 4 values of x

Yeah solve for cosx @fleet mauve

#

Move the 1/3 then do a sqrt

#

@kind anvil it is a unit circle angle

#

Or rather value

kind anvil
#

tangent of some angles is sqrt(1/3) but not cosine

fleet mauve
#

i am still a little confused

#

can you give ma a step by step of the solution?

novel thicket
#

Rationalize it @kind anvil

#

Oh yeah mb

#

Too early

kind anvil
#

f

novel thicket
#

Should be /2

fleet mauve
#

im lost

kind anvil
novel thicket
#

I expect a response for that

fleet mauve
#

brother idk man 😢

#

-1/3?

kind anvil
#

how do you solve c^2 - 1/3 = 0

novel thicket
#

If 3-1 =2 how do you move the 1

fleet mauve
novel thicket
#

Yeah

fleet mauve
#

to each side

novel thicket
#

So why did you subtract 1/3

fleet mauve
#

mb mb

novel thicket
#

So what should it be

fleet mauve
#

i acc dont know man

novel thicket
#

Cant help you sorry

fleet mauve
#

wait wait

#

r u asking me to move the 1/3 to the other side

novel thicket
fleet mauve
#

soo i add 1/3 on each side then?

kind anvil
#

yes

fleet mauve
#

kk then what

kind anvil
#

then what do you have

fleet mauve
#

cos^2x=1/3

kind anvil
#

yes now just solve for cos(x)

fleet mauve
#

2pi?

kind anvil
#

what

#

don't just guess

#

try to figure it out

fleet mauve
#

damn im strugglin hold up

#

cant figure it out man sorry

#

can u help me with that @kind anvil

kind anvil
#

i most likely cannot help you at this point but i can try

#

how do you isolate a variable in an equation
