Hi everyone this is my first time here - I'm completely confused not so I thought I may as well ask complete stangers for help!
the question is..
Determine whether the following limit exists. If so, find its value.
lim [sin(x^2+y^2+z^2)] / (x^2+y^2+z^2)^1/2
first, how can i prove that the limit is exist?
i'm thinking of to get the above limit to be something like
[sin (x)]/x = 1
should i use quotient rule..?
hope that someone can guide me solving this question..
