Okay, so in this section we're asked to parameterize the line connecting minus 1 .5 to 1 -2.
00:14
So let's start thinking of the, let's just maybe a quick recap.
00:22
So the line, if i want to connect a to b, the easiest way is to connect is to define the line that, and i want it to be at a at times equal.
00:35
Time t equals zero and i want it to be at b at time t equals one, this will always be the line, 1 minus t times a plus t times b, right? whatever a and b are, a and b can be in any dimension.
00:50
So at t equals zero, i'm starting at a, right? this guy is zero.
00:53
At t equals one, this disappears and we get b, right? this seems like i wrote r prime, but it was just a glitch of my pen, right? r of t.
01:00
So in our case, the line that we are searching for will be the line r of t, which is defined by 1 minus t times minus 1, 5 plus t times 1 2.
01:17
And we just solve this equation, really...
