Question

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

Answer 1

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

Answer 2

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

Answer 3

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

Answer 4

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

Answer 6

you can use that

Answer 7

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

Answer 8

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

Answer 9

thank you

Answer 10

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