Solve Lim as x->0 of -x/tan(3x)

OpenStudy (anonymous):

can you maybe write tan(3x) as something different, using the trig properties

OpenStudy (anonymous):

sin(3x)/cos(3x) right?

OpenStudy (anonymous):

thats looking good

OpenStudy (anonymous):

well then the equation becomes -x * co(3x)/Sin(3x)

OpenStudy (anonymous):

hold on my friend

OpenStudy (anonymous):

oh okay yes, correct

OpenStudy (anonymous):

and then (-x/sin(3x)) * cos(3x)

OpenStudy (anonymous):

hmm

OpenStudy (anonymous):

what is the next step? that is were i get confused

OpenStudy (anonymous):

oh man i forgot about you, let me think for a bit
