All right, so this is a very interesting question here.
00:04
We're looking for parameter equations for a helix that is centered on the x -axis of the radius 5.
00:10
So let's look at a helix is a spiral, right, or if you look at it dead on it just ends up being a circle, right, because all the helix sits on top of itself.
00:24
So if we look at it dead on, it's saying centered at the x -axis, which means that the x -axis should be pointing directly at us in the yz -plane.
00:33
This will look basically like a circle, right, essentially this has radius 5, so this circle has parameterization yz of 5 times cosine t, 5 times sine t.

My 5s look like s's, pay that no mind, let's change that a little bit, 5, 5...
