All right, in this problem, we're going to be converting from cylindrical to rectangular coordinates.
00:05
So if we have a cylindrical coordinate characterized as r, theta, and z, we're going to translate that to our rectangular coordinate of x, y, and z.
00:18
So we know that this transformation is done by x equal to r cosine theta, y equal to r cosine theta, y equal to r sine theta, and z is equal to z.
00:33
So let's look at the first coordinate.
00:35
So up first we have four, pi over six, and three.
00:43
This is going to be something, something, three.
00:48
So x is equal to, so r is four, cosine of pi over six.
00:55
So that's going to be equal to four over rad three.
01:02
And that seems wrong.
01:06
So yeah, it should be two.

Oops, sorry, that is not right now...
