Homework Statement
lim
(x,y) --> (0,0) [sin(2x) -2x + y]/[x^3+y]
Homework Equations
The Attempt at a Solution
so I tried approaching from the x-axis and I got
y=0 lim x-> 0 [sin(2x) -x + 0]/[x^3 + 0] which gives me 0/0
and from the y axis
y=0 lim y ->0 which gives me lim y-> 0 y/y = 0/0
if I try approaching from a line such as y = x I also get 0/0
what do I do now? L'hopitals rule? If so I'm not sure how to use it here...
