QuestionFind the values of: (a) $\sin \frac{\pi}{3}$, (b) $\cos \frac{2 \pi}{3}$, and $\tan \frac{7 \pi}{4}$ in surd form.

Studdy Solution
(c) We need to find the value of $\tan \frac{7 \pi}{4}$.
This is a standard value in trigonometry. The tangent of $\frac{7\pi}{4}$ is $1$.
So, $\tan \frac{7 \pi}{4} =1$.
The values of the trigonometric functions are(a) $\sin \frac{\pi}{3} = \frac{\sqrt{3}}{2}$ (b) $\cos \frac{2 \pi}{3} = -\frac{1}{2}$ (c) $\tan \frac{7 \pi}{4} =1$
