Homework Statement Given 0≤x<2pi, solve tan x/2 > -1 The Attempt at a Solution I thought I would set tan x/2=-1 but I'm not sure. Is the answer 0<x<pi, 3pi/2<x<2pi?

Haha yeah. I realized I put it the other way.. that's why I couldn't factor it, which is why I deleted it from my post ^^ Silly me. Hmm okay I will go check my work on my second derivative. Thank you so far!

Sorry for bumping this thread but I have another question. Is there a point of inflection? I got my second derivative and set it equal to 0 and I got this x^3-3x^2-3x-3=0. How do you factor it to prove that there is or isn't a point of inflection.

Hmm okay because I know when x=1, y=1, so does that mean I have to note that the asymptote y=1 is for when X<0 and X>0? Thanks for helping!
