find the set of values of x for which [tex] 2x > \dfrac{3x + 1}{x+1} [/tex] done this and got [tex] -1<x<-0.5, x > 1 [/tex]
b) find the set of inequalities where
[tex] 2sint > \dfrac{3sint + 1}{sint + 1} [/tex] where [tex] -\pi < t < \pi [/tex]
first I found the set values of t suitable in the range for -1,-0.5,1 which I got to be as [tex] -\frac{\pi}{2}, - \frac{\pi}{6}, - \frac{5\pi}{6}, \frac{pi}{2} [/tex] and hence getting [tex] \frac{-5\pi}{6} < t < \frac{-\pi}{6}, t > \frac{\pi}{2} [/tex]
however I'm not sure if it is correct, and if it isn't I don't know how else to do it.
