WebThat's the square root of 8. And the square root of cosine squared theta is going to be cosine theta. Now, you might be saying, hey, wait, if I take the square root of something squared, then wouldn't that just be the absolute value of cosine theta? In order to take away the absolute value, I'd have to assume that cosine theta is positive. Web$\begingroup$ @AmanuelBogale Remember that cosine is positive in the first and fourth quadrants. The fourth quadrant angle with reference angle $\pi/4$ is $2\pi - \pi/4 = 7\pi/4$. Alternatively, $\cos(-x) = \cos x$, so $\cos(-\frac{\pi}{4}) = \cos(\frac{\pi}{4})$. Note that $7\pi/4$ is coterminal with $-\pi/4$. $\endgroup$ –

So it could be the positive or negative square root of 3/4. So cosine of theta could be equal to the positive or negative square root of 3 over 4, which is the same thing as the positive or negative square root of 3, over the square root of 4, which is 2.

Webcos (θ)=cos (θ+2pi) ... and yes, there are lots of others - technically, an infinite number of others since sin and cos are periodic and repeat every 2pi, positive or negative. So, for example, sin (θ)=sin (θ+2npi), where n is any integer. I'd probably add to the list: sin (-θ)=-sin (θ) …
