To find the exact value of the expression cos 180 degrees - sin 180 degrees, we first need to evaluate each trigonometric function separately.

Calculating Cosine and Sine Values

  • cos 180 degrees: The cosine of 180 degrees is -1.
  • sin 180 degrees: The sine of 180 degrees is 0.

Putting It All Together

Now, substitute these values into the expression:

cos 180 degrees - sin 180 degrees = -1 - 0

Final Result

The exact value is -1.
