# Which of the following is not a possible value of sin x?

# A) 2 B) -1 C) 1 D) 0.5

Trigonometric functions have a specified domain and range defined for them.

## Answer: The value which is not possible for sin x is option A) 2.

We can make use of the graph of the trigonometric functions to study their range.

**Explanation:**

Given:

Option A) 2

Option B) -1

Option C) 1

Option D) 0.5

The value of sin x lies in the range between -1 to +1 on the number line. All real numbers within this range are included, while all those beyond this range are excluded. Both sin x and cos x have the same range, therefore an impossible value for a sine will also be an impossible value for the cosine.

### Hence, the value which is not possible for sin x is option A) 2.
