This point (-3, 4) is on the terminal side of an angle \theta in standard position.
would \sin\theta=4?

Answer 2

Hmm this doesn't appear to be on the unit circle.
when we're writing our coordinates in terms of sines and cosines it will look like,
\( (r \cos \theta, r \sin \theta)\).

So I think what we actually have is \(r \sin \theta=4\)

And based on our picture we can determine the radius fairly easily using the Pythagorean Theorem.

Sorry for the late response :C got busy.
