Answer 2

Calculating Trigonometric Expressions

To calculate the expression sin 2004° cos 1974° - sin 1974° cos 2004°, we can use the trigonometric identity:

sin(A)cos(B) - sin(B)cos(A) = sin(A - B)

So, the expression simplifies to sin(2004° - 1974°).

Solution

Using the trigonometric identity, we have: ``` sin(2004° - 1974°) = sin(30°) ```

Final Result

Therefore, the value of the given expression is sin(30°).
