Okay, now let's look at this problem. Problem number 3. Okay, so we have sign of 2 pi over 3. So

Question

\sin\left(\frac{\pi}{2}\right) = \cos\left(\frac{3\pi}{2}\right) = \tan\left(-\pi\right) = \cot\left(-\frac{\pi}{4}\right) = \sec\left(\frac{\pi}{4}\right) = \csc\left(\frac{\pi}{3}\right) =

          \sin\left(\frac{\pi}{2}\right) = \cos\left(\frac{3\pi}{2}\right) = \tan\left(-\pi\right) = \cot\left(-\frac{\pi}{4}\right) = \sec\left(\frac{\pi}{4}\right) = \csc\left(\frac{\pi}{3}\right) =
