Question

Find all the angle values that fit the trigonometric expression. I picked the last one as my answer, but I'm not sure. (picture in attachment)

Answer 1

I picked the last option because I know 2pi(n) is 360 around the circle, but pi falls 180 degrees apart, so I figured pi(n) would work too?

Answer 2

when is tangent 0

Answer 3

At pi

Answer 4

On the Unit Circle

Answer 5

when cos = -1 or 1 so at 0 and pi

Answer 6

180 degrees too

Answer 7

Yeah

Answer 8

Would the answer I pick work? Or was I wrong about the 2pi(n) and pi(n) thing :o I see that there are two spots on the Unit Circle that fit the trigonometric expression and they're at half the circle so 360 adn 180 degrees around would work? aka 2pi(n) pi(n)?
