Alright, this problem is asking to describe the relationship between right triangle circles and trigonometric functions.
00:08
So if i drew a coordinate grid and i wanted a right triangle on there, that right triangle of course has a 90 degree angle on there, right? we know that this guy over here is going to be the hypotenuse of our right triangle and these are our legs, right? so that's what makes that a right triangle.
00:36
Then if we were to put that in a circle, this could be any coordinate on that circle and notice this leg over here is our x value and this leg over here is our y value.
01:06
So the distance from the center to any point on that circle is going to be the radius.
01:13
So the hypotenuse here also represents the radius of the circle, okay? so there's our relationship between our triangle and our circle.
01:31
Then we have to figure out how this relates to a trig function.
01:37
Well there are three very common trig functions, sine, cosine, and tangent.
01:47
Sine is referred to as opposite over hypotenuse in these triangles...
