We learned that sine of theta over cosine of theta is equal to tangent of theta. .
When theta is equal to 3 pi over 2, cosine of theta is equal to 0.
so cosine of theta is-- cosine of 0 is 1.
So we get r sine of theta minus 2r cosine of theta is equal to minus 3.
And so we see that we do indeed have the same value for cosine of theta and sine of theta right there.
a theta right there, we take the cosine of theta, it has to be equal to x.
Let's say that we have the polar coordinates r is equal to sine of theta plus cosine of theta.
non-inverse function tangent--that's equal to the sine of theta over the cosine of theta.
which is equal to 1 over cosine of theta.
so side e is equal to c minus b cosine of theta.
We're just left with a b squared plus c squared minus 2bc cosine of theta.
it's very easy to figure out the cosine of theta, right?
I'm going to graph h of theta is equal to 9 minus 8 cosine of theta.
So let's try to graph h of theta is equal to 9 minus 8 cosine of theta.
That's interesting because that's also equal to sine of theta over cosine of theta.
With that out of the way, we say that cosine of theta is equal to adjacent over the hypotenuse.
So in this case cosine of theta is equal to the adjacent side, which has length 4, over the hypotenous which has the length square root of 65.
At how many points do the graphs of y equals sine of theta and y equals cosine of theta intersect for this range for theta? .
b cosine of theta.
You could view the dot product as-- and I did this in the dot product video-- you could view it as a cosine of theta, b.
