allright sorry for asking a million questions..but this one is weird also.

the limit as x goes to 0 ((e^x) - 1) times cosx

the answer in the book is 1 but I always get an undefined answer when I put that limit into a fraction. (either the cosx on the bottom of the fraction..((e^x) - 1)^-1/cosx..or secx/e^x - 1 both give me invalid answers.) Thx for the help.

edit..ok I looked online for the mistakes in book. It should be ((e^x-1) times cotx
