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

The question is given below as

`\tan\theta(x)=1`

Step 1:

Divide both sides by tan theta

`\begin{gathered} (\tan(\theta)(x))/(\tan\theta)=(1)/(\tan\theta) \\ x=(1)/(\tan\theta) \\ x=cot\theta \end{gathered}`

Hence,

The final answer is

`\Rightarrow cot\theta`

OPTION D is the right answer
