Three-sided (adj) having three sides, especially three plane sides; as, a three-sided stem, leaf, petiole, peduncle, scape, or pericarp
As a approaches 3 from left, (a â 3) is negative and âa - 3â = - (a - 3); Hence, Lim aâ3- (âa - 3â)/ (a - 3) = - (a - 3)/ (a - 3) = -1; This is the required answer for this one sided limit.
