That -1 is suppose to represent the inverse. Basically, I've
narrowed things down the 4th quadrant (ASTC), and I've reduced
the problem down to: Alright, we also have Opposite over
Adjacent as well (TOA), so therefore what would we be working
with to create the formula (Pythagorean Theorem) needed to solve
the question? Or to make things more precise, how exactly would
this triangle and equation look if everything were to be plugged
in correctly given the details I have gathered about the
problem? Furthermore, what roll is the secant function going to
play when I finally solve the inside of the inverse tangent
function? And finally, what is the difference between what is
being asked of the problems... one is asking for the exact
evaluation, while the other is asking for an identity. Our
professor hasn't gotten much into depth of any of this stuff,
but I got a worksheet due tomorrow on it, so I'm kind of on my
own here. And I also apologize if I'm not clear at all on my
explanations, as I'm extremely tired as
