So cosine of theta is equal to 1.
So theta is equal to 53.13 degrees.
So tangent of theta is equal to 4/3.
When theta is equal to 2 pi, sine of theta is equal to 0.
Psi plus psi is 2 psi minus theta is equal to 0.
When theta is equal to 0, sine theta is 0.
This is the same thing as sine of theta is equal to y/r, right?
When theta is equal to pi, sine of theta is 0.
We know that cosine of theta is equal to d over b, right?
When theta is equal to pi over two, sine of theta is one.
And this is the same thing as cosine of theta is equal to x/r.
Tangent of theta is equal to y/x.
Now, by definition,this means that the cosine of theta is equal to x.
So now sine of theta is equal to negative 1.
So when theta is equal to 0, you're at this point right over here.
So we know that a cotangent of theta is equal to 1 over tangent theta. .
When theta is equal to pi, sine of theta is 0 again.
You could write it as the arctan of the tangent of theta is equal to the arctan of 4/3.
So you get six theta is equal to pi over two plus n pi.
So we have got our first main identity here,that the cosin of theta is equal to the sin of pi over two minus theta. .
Tangent of theta is equal to cotangent of five theta. .
Let's divide both sides by six, we get theta is equal to pi over twelve plus pi n over three.
When theta is equal to pi 2, cosine of theta is 0.
Let's add four theta to both sides of this equation,we get six theta is equal to pi over two, this is cancelled out, plus two pi n.
Cosine of theta is equal to the x-coordinate of this point.
Our new definition of the trig functions was that sine of theta is equal to the y-coordinate, right, this is y-coordinate where it intersects the unit circle.
So when theta is equal to zero, sine of theta is zero.
