tan(360°- x) * sin(90°-x)
Answered by oobleck
sorry - tan(360° - x) = -tan(x)
so tan(360°- x) * sin(90°-x) = -tanx * cosx = -sinx
Answered by GPT 3.5
To simplify the expression, we can use the following trigonometric identities:

- tan(360° - x) = tan(x)
- sin(90° - x) = cos(x)

Therefore, the expression becomes:

tan(x) * cos(x)

Yes, you are correct. I apologize for the oversight.

The correct simplification is:
tan(360°- x) * sin(90°-x) = -tan(x) * cos(x) = -sin(x)
