Question

The value of $\cot 0°$ is:

• A. $0$
• B. $\frac{1}{2}$
• C. Undefined
• D. $1$

Answer 1

The correct option is C

Undefined

Value of $\cot 0°$.

Explanation for the correct option:

Option (C): Undefined

Apply trigonometry formulas and we can represent and solve $\cot 0°$ as follows:

$$\begin{gathered} \cot (0°)=\frac{\cos (0°)}{\sin (0°)} \\ \Rightarrow \cot (0°)=\frac{1}{0} \\ \Rightarrow \cot (0°)=\infty \end{gathered}$$

Hence, option (C) Undefined is correct.

Explanation for the incorrect options:

Option (A), (B), (D): Since $\cot 0^{\mathrm{o}}$is calculated as $\infty$.

Hence, option (A), (B), (D) are incorrect.

Hence, option (C) Undefined is the correct option.
