Okay, so here's the situation, okay? then we need to parameterize c1.
00:05
C1 is 1 minus t.
00:11
So we're going to use this technique and i'm going to show you one of them and then just figure out the others, you know.
00:23
So then r of t is 2t, 0 and 0 and t is 0 to 1 and c2 is r of t, 1 minus t.
00:38
This time from 2, 0, 0 to 2, 5, 1.
00:47
So then r of t is 2 minus 2t, so 2 and then 5t and t.
00:56
Once again, 0 to 1 and then c3 is r of t, 1 minus t, 2, 5, 1, 2, 0, 5, 1.
01:13
So then r of t is 2 minus 2t, 5 minus 5t, 5 and then 1 minus t, 1.
01:25
Once again, 0 to 1 and then lastly, r of, i mean c4 is 1 minus t, 0, 5, 1, 2, 0, 0, 0.
01:43
So then r of t is 0, 5, minus 5t and then 1 minus t, okay? and once again, 0 to t, 1 and we're going to calculate f dot dr and all the cs.
02:06
So for this, we need to calculate the drs also.
02:12
Drs are 2, 0, 0 for that one.
02:17
For this one, 0, 5 and 1...
