SUMMARY
The equation Cos X * [Cosec (270+X)][tan X] simplifies to -tan X, as confirmed by the discussion participants. The key transformation involves recognizing that Cosec (270+X) equals -sec X, leading to the conclusion that Cos X * -sec X * tan X results in -tan X. This solution is definitive and no alternative solutions were presented in the discussion.
