Question
Find the following function values without using a calculator.$$\cot -\frac{3 \pi}{4}$$
Step 1
The function is cotangent, denoted as $\cot$, and the angle given is $-\frac{3\pi}{4}$. Cotangent is defined as the ratio of the cosine of an angle to the sine of that angle, i.e., $\cot \theta = \frac{\cos \theta}{\sin \theta}$. Show more…
