Okay, we're going to represent the vector valued function with the given parameters, and we're going to sketch the space curve to see what the intersecting surfaces look like.
00:10
So because we're in that first quadrant, that's placing where x, y, and z are all positive.
00:19
And so as we draw this, we can think about that.
00:23
Now, x does equal t, and you can see that we have the y squared, plus z squared equals four, and x squared plus z squared equals four.
00:36
So if you consider your xz plane, it doesn't matter what y is.
00:41
It's going to be a circle, and you can continue that circle all the way, you know, with the y -axis in the center.
00:49
With y squared plus z squared equals four, you can do the same thing, but now x is going to be in that center.
00:58
So you can see that these circles, do intersect.
01:02
So to just look at that first positive quadrant, i will make a second sketch so you can see where they actually intersect...
