Limits I'm doing some online practice work... and I can't find out how to get the following two limits.... I know they are not undefined. The limit as x approaches 0 of sin^2(4x) / xtan(x) .. I tried to flip it... but I couldn't get it that way either. The limit as x approaches 0 of (x + tan(4x)) / sin(9x) Any help would be appreciated.
