Question Express 16sin(50r)sin(23r)16 \sin (50 r) \sin (23 r) as a sum or difference of trigonometric functions.

Studdy Solution
Write the final expression as a sum or a difference:
16sin(50r)sin(23r)=8[cos(27r)cos(73r)]16 \sin (50r) \sin (23r) = 8[\cos(27r) - \cos(73r)]
The product 16sin(50r)sin(23r)16 \sin (50r) \sin (23r) is written as a difference 8[cos(27r)cos(73r)]8[\cos(27r) - \cos(73r)].
