27. F(x, y) = sin(xy)/(e^x - y^2)
Use polar coordinates to find the limit. [If (r, theta) are polar coordinates of the point (x, y) with r >= 0, note that r --> 0+ as (x, y) --> (0,0).]
lim (as (x,y) --> (9,0)) of (x^3 + y^3)/(x^2 + y^2)
Use spherical coordinates to find
lim (as (x,y,z) --> (0,0,0) of xyz/(x^2 + y^2 + z^2)© BrainMass Inc. brainmass.com March 21, 2019, 2:29 pm ad1c9bdddf
