3. Evaluate the following limits. You must state the indeterminate form before applying L'Hopital's Rule! (a) lim where a is a non-zero real number. (b) lim x In r 1-+0+ Hint: xInx= (c) lim COS I -I *(d) lim In cos r Hint: You will need to apply L'Hopital's rule twice. Recall that tan(0) = 0 and sec(0) = 1. == *(e) lim(1+r)* (Hint on next page)
