we get six theta is equal to pi over two, this is cancelled out,
So we know that a cotangent of theta is equal to 1 over tangent theta. .
Or t is equal to 0, theta is equal to 0, so cosine of theta is-- cosine of 0 is 1.
Our new definition of the trig functions was that sine of theta is equal to the y-coordinate, right,
Let's divide both sides by six, we get theta is equal to pi over twelve plus pi n over three.
I'm going to graph h of theta is equal to 9 minus 8 cosine of theta. .
If we said what is sine of theta when theta is equal to pi over 2.
we say that cosine of theta is equal to adjacent over the hypotenuse.
When theta is equal to 3 pi over 2, sine of theta is negative 1.
So we get r sine of theta minus 2r cosine of theta is equal to minus 3.
So when we said when theta equaled 0, sine of theta is equal to 0.
sine of theta minus 2 cosine of theta is equal to minus 3.
what is cosine of theta when theta is equal to 0?
When theta is equal to pi over 2, sine of theta is equal to 1.
We can also specify it by r is equal to 5, and theta is equal to 53 degrees.
When theta is equal to 3 pi over 2, cosine of theta is equal to 0.
And we also learned in previous videos that the sine squared theta plus the cosine squared of theta is equal to 1.
So cosine of theta is equal to adjacent over hypotenuse, and then the tangent of theta is equal to opposite over adjacent.
So that just says sine of theta over cosine of theta is equal to tangent of theta. .
And then, of course, you can-- in case I haven't done it already, you now know that sine of theta over cosine of theta is equal to tangent of theta.
