The huge difference is that sine of theta has a direction.
Now we're going to graph sine of theta.
So we know that from SOH-CAH-TOA we know that sine of theta is equal to the opposite over the hypotenuse.
So if you know the sine of theta, it's very easy to figure out the cosine of theta, right?
When theta is equal to 3 pi over 2, sine of theta is negative 1.
So that just says sine of theta over cosine of theta is equal to tangent of theta. .
So cosine of theta is negative square root of 2 over 2. And sine of theta is also negative square root of 2 over 2.
And the sine of theta is the y-value on the unit function-- on the unit circle.
We learned that sine of theta over cosine of theta is equal to tangent of theta. .
And so we see that we do indeed have the same value for cosine of theta and sine of theta right there.
So the sine of theta 1 is going to be the opposite of the angle over the hypotenuse.
If we said what is sine of theta when theta is equal to pi over 2.
I'm gonna use that to figure out the values of sine of theta for a given theta.
So sine of theta, so we're at 2 pi, sine of theta is now 0 once again.
So 3 times y, well, y is the same thing as r sine of theta minus 7 times x.
And so if where it intersects the unit circle is at 1 comma 0, then sine of theta is just the y-coordinate.
I guess it's just for convenience because you know everyone knows it's just 1 over sine of theta.
So when we said when theta equaled 0, sine of theta is equal to 0.
And say, I immediately know that sine of x, or sine of theta is square root of 3 over 2.
Then when we got to 2 pi-- when we got to theta equal to 2 pi, sine of theta, again, equaled 0.
