and how can we help you with this
limx→0 sin x / 2x2-x
I'm supposed to find the limit graphically (which I did; it's -1) and confirm it algebraically. I started by factoring the denominator 2x2-x to x(2x - 1). I'm trying to get rid of that x factor in the denominator but I have no clue what to do with the numerator sin x.
