Exercise: forum.jpg In question c, the answer is does not exist because "As t approaches 0 from the left, f(t) approaches -1 and as t approaches 0 from the right, f(t) approaches 1". The solution above is from Thomas-Calculus 13th edition. I can not understand the order... Why f(t) approaches -1 from the left and not the opposite? To me it seems the opposite. As f(t) approaches 0 from the left, f(t) approaches 1 and as t approaches 0 from the right, f(t) approaches -1. Last edited by babaliaris; July 4th, 2019 at 04:32 AM.
