(1 point) Evaluate the following limit: lim 3x + tan(3x) x-0 4x - tan(3x) Enter -Inf if your answer is -co, enter Inf if your answer is co, and enter DNE if the limit does not exist. Limit = (1 point) Find the following limits, using I'HVopital's rule if appropriate 2 arctan(x') lim x -+ 0o lim x In(x) = x-0+ (1 point) 3 Find the limit. Use I'Hospital's Rule if appropriate. Use INF to represent positive infinity, NINF for negative infinity, and D for the limit does not exist. lim 8xIn(2)/(3+In(x)) = 1 -+ 00 (1 point) For what values of a and b is the following equation true? 4 lim sin(2x) -+at = 0 x-0 x3 b =
