## Homework Statement

lim as (x,y,z) ->0,0,0 of xyz/(x^2+y^2+z^2) it says (HINT: use spherical coordinates)

## Homework Equations

## The Attempt at a Solution

I tried putting it in spherical coordinates but it didn't seem to help. I ended up getting pcos(theta)sin(psi)p(sin(theta)sin(psi))pcos(theta)/(p^2cos^2(theta)sin^2(psi)+p^2sin^2(psi)sin^2(theta)+p^2cos^2(psi))

I don't know what I can do with this messy thing or even why theywould tell me to use it just looks like it made it worse. By the way my teacher said we must use spherical coordinates or we will receive no credit.
