lenny, the PM thing is stuffing up as i can view PM's, but can send them. i've done trig ratios, equations, identities, regions, unions and intersections, inequalities, inequalities w/ x in denominator. i'm doing perms and combs and 3D trig ATM at school, but i don't feel confident enough to be tested on those. i think this wednesday would be a good day. PM me back in further detail.
