Complete the general solution to y = cos-1(1) for K a whole number.

Question

freckles · Answer

what is K
and are you suppose to just evaluate $$\arccos(1)?$$

anonymous · Answer

No idea....this is how the problem is stated with no further instructions

freckles · Answer

you can find this on the unit circle just solve for cos(y)=1 
where y is some number between 0 and pi

freckles · Answer

for what angle between 0 and pi do you cos is 1?

freckles · Answer

freckles · Answer

you can use that

freckles · Answer

and remember cos is the first value in the ordered pair
and sine is the second value in the ordered pair

freckles · Answer

so you should see an angle between 0 and pi such that cosine is 1

anonymous · Answer

thank you

freckles · Answer

what angle (in radians) do you see such that cosine is 1?
