Best ResponseYou've already chosen the best response.0Is it zero? Separate the two and multiply out. It is either zero or indeterminate, but I'd go with zero.

Best ResponseYou've already chosen the best response.3Using the l'Hôpital's rule: Take derivative of the top and the bottom: tan3x = 3sec²3x 3tan2x = 6sec²2x So its: 3sec²3x/6sec²2x Now plug in x=0 You'll get 3(1)/6(1) = 3/6 =1/2

Best ResponseYou've already chosen the best response.0Thanks all for your help. Any solution without that rule for now? Because the teacher said that we should be able to do this question without any rules. I wasnt taught l'hopitals rule yet

Best ResponseYou've already chosen the best response.0It would be zero. Divide and conquer; veni vidi vici. Tan... * tan... will both go to zero, multiply out and you will get zero.

Best ResponseYou've already chosen the best response.1see in numerator u xpand tan 3x and do the same for 6tan 2x in denominator and then put x=0 and u'll get 1/2

Best ResponseYou've already chosen the best response.1means apply formula for tan 3x and u'll get everything in tan x same u do in denominator and then put x=0 to get ur result
