The value of `Sin (Cos 90)` is equal to

Options

A. -1
B. 0
C. 1
D. None of these

Answer

To solve the question "The value of Sin (Cos 90) is equal to", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the inner function**: We need to find the value of Cos 90.
\[ \text{Cos } 90^\circ = 0 \]

2. **Substitute the value into the outer function**: Now we substitute the result from step 1 into the sine function.
\[ \text{Sin (Cos } 90^\circ) = \text{Sin } 0 \]

3. **Calculate the sine of 0**: We know that the sine of 0 degrees is:
\[ \text{Sin } 0 = 0 \]

4. **Final result**: Therefore, the value of Sin (Cos 90) is:
\[ \text{Sin (Cos } 90^\circ) = 0 \]

### Final Answer:
The value of Sin (Cos 90) is **0**.
