1?cos 6t Limits? Evaluate the following limits. Use l'Hôpital's Rule when needed. lim t?0 2t

Solution Step 1 In this problem we have to evaluate the limit lim 1cos 6t by using l'Hôpital's Rule t0 2t l'Hôpital's Rule: f(x) 0 f(x) ± Suppose that we have one of the following cases, lim g(x)= 0 or lim g(x) = ± xa xa Where a can be any real number, infinity or negative infinity. In these cases we have lim f(x)= lim f(x) xa g(x) xa g(x)
