So let's see how we can get from that SOH-CAH-TOA definition to this unit circle definition, and why they're actually consistent with each other.
If you don't remember the unit circle, maybe you will want to rewatch the videos we have on that.
You could draw the triangle and the unit circle, if you don't believe me,
They can be extended to the full set of real arguments by using the unit circle, or by requiring certain symmetries and that they be periodic functions.
The unit circle definition provides little in the way of practical calculation;
And we have actually extended this with the unit circle definition, but if you watch those videos, you will realize that the unit circle definition directly uses SOHCAHTOA.
And the cosine of an angle as defined on the unit circle definition is the x-value on the unit circle. .
you're at the equivalent point on the unit circle.
if you remember from the previous video, why we needed the unit circle definition.
It tells us if we have a unit circle-- And this is a picture of a unit circle here.
And if you go back to some previous modules you will remember that that's exactly what the sine function was equal to when we looked at the unit circle.
I think it actually has some obvious properties and if you were to draw unit circle and all of that too.
don't have this memorized, you should draw the unit circle.
using height expressions and different unit circle positions.
I could draw it out, but I think-- you might want to draw the unit circle and figure it out for yourself,
-1-√2 are outside the unit circle(shown in red,
will kind of verge on the unit circle definition anyway.
The unit circle definition tells us that the cosine of this angle is equal to the x-coordinate where this radius intersects the unit circle, and that the sine of this function is equal to the y-coordinate where this point intersects the unit circle.
a pole of an unstable system that is outside of the unit circle can be canceled and reflected inside the unit circle.
to be the same, but now the direction of-- and we're kind of assuming this is all on the unit circle.
