# If ,then

Hint:

### we have given trigonometry function. Which is

We have to find where θ is belongs. Solve the function and find the answer.

## The correct answer is:

### Here, We have to find where θ is belongs.

Firstly, we have given

---(1)

[since, ]

We know that,

For every θ for sin and cos is . so for But θ not possible in second quadrant because cos is negative,

Then θ always belongs to ( 0 , ).

Therefore the correct answer is θ ∈ ( 0 , ).

In this question, we have given equation, where we have to find where the θ belongs. For all value of sin θ cos θ = so θ always lies between ( 0 , ) .
