Question

(tan 0) (x) = 1 where x is a trigonomic function. Which of the following functions substituted for x solves the above equation?

Answer 1

Answer:

The question is given below as

$\tan\theta(x)=1$

Step 1:

Divide both sides by tan theta

$\begin{gathered} \frac{\tan(\theta)(x)}{\tan\theta}=\frac{1}{\tan\theta} \\ x=\frac{1}{\tan\theta} \\ x=cot\theta \end{gathered}$

Hence,

The final answer is

$\Rightarrow cot\theta$

OPTION D is the right answer
