evaluate then simplify:
tan80 - tan35
_____________
1+ tan80 (tan35)
that above is all a fraction.
i need to make it equal to something simplier but i don't know what to substitute into the tangent angles. i don't see a way other than using the decimals but then i won't get an exact answer. i could incorporate like tan80= tan(30+50) but 30 and 50 aren't easy angles to have the tangent defined in a fraction like the angles of 15, 30, 45, and 90 are. any ideas?
