Answer 2

To calculate the value of the expression sin(34°) × cos(26°) - sin(19°) × cos(11°), follow these steps:

1. Convert the angles from degrees to radians, as trigonometric functions often work with radians:

   • 34° = 34 * (π / 180) radians
   • 26° = 26 * (π / 180) radians
   • 19° = 19 * (π / 180) radians
   • 11° = 11 * (π / 180) radians

2. Calculate the trigonometric values:

   • sin(34°) = sin(34 * (π / 180))
   • cos(26°) = cos(26 * (π / 180))
   • sin(19°) = sin(19 * (π / 180))
   • cos(11°) = cos(11 * (π / 180))

3. Substitute the calculated values into the expression:

   • Result = sin(34 * (π / 180)) × cos(26 * (π / 180)) - sin(19 * (π / 180)) × cos(11 * (π / 180))

You can use a calculator or a programming language with trigonometric functions to perform the actual calculations. If you'd like, I can help you with the calculations using Python. Just let me know!
