Find the Trigonometric Equation for tan (π - u)?
Just took a test that I'm pretty sure I bombed so I wanna see if I got this right.
Do I just plug it into that "Functions of the Difference of Two Angles" equation and I'm done?

tan (π - u)
=tanπ - tan u / 1+ tanπ tan u
= 0 - tan u / 1+ 0
=-tan u
note: tan π = 0
i hope you simplified.
