Video transcript - [Instructor] We're asked to convert degrees and negative 45 degrees to radians. Let's think about the relationship between degrees and radians, and to do that, let me just draw a little circle here.

So that's the center of the circle, and then do my best shot, best attempt to freehand draw a reasonable-looking circle. That's not, I've done worse than that. Alright, now, if we were to go in degrees, if we were to go one time around the circle like that, how many degrees is that? We know that that would be degrees. If we did the same thing, how many radians is that, if we were to go all the way around the circle?

We just have to remember, when we're measuring in terms of radians, we're really talking about the arc that subtends that angle. So if you go all the way around, you're really talking about the arc length of the entire circle, or essentially the circumference of the circle. And you're essentially saying, how many radius's this is, or radii, or how many radii is the circumference of the circle.

You know a circumference of a circle is two pi times the radius, or you could say that the length of the circumference of the circle is two pi radii. If you wanna know the exact length, you just have to get the length of the radius and multiply it by two pi.

That just comes from the, really, actually the definition of pi, but it comes from what we know as the formula for the circumference of a circle. If we were to go all the way around this, this is also two pi radians. That tells us that two pi radians, as an angle measure, is the exact same thing, and I'm gonna write it out, as degrees.

And then we can take all of this relationship and manipulate it in different ways. If we wanna simplify a little bit, we can divide both sides of this equation by two, in which case, you are left with, if you divide both sides by two, you are left with pi radians is equal to degrees. How can we use this relationship now to figure out what degrees is? Well, this relationship, we could write it in different ways. We could divide both sides by degrees, and we could get pi radians over degrees is equal to one, which is just another way of saying that there are pi radians for every degrees, or you could say, pi over radians per degree.
