Evaluate the following limits, assuming all angles are in radian
a) lim x->0 (sin5x)/(sin6x)
b) lim x->0 (xsin6x)/(sin^2(9x))
c) lim x->0 (sin3x)/(9x-2tanx)
lol that's just my signature and has nothing to do with you or this post, but let me do the first one and have you try the second one
is indeterminant, meaning you get if you try to plug into the expression, so we apply L'hospital's rule to get
do the same thing for the next
