All right, so co -sequent and secant.
00:03
Seekin is one over cosine, so cosine cannot be zero, okay? and cosine is zero when x is multiples of pi over two.
00:16
So, by the way, both functions in the cartesian coordinate system.
00:26
So this is negative pi over two.
00:29
This is pi over two.
00:31
And here's cosine is one.
00:34
So this is the second curve, okay? so, and this is the, like, a little more, 3 pi over 2, and pi, um, cosine of pi negative 1.
00:59
So this is pi right there...
