lim ( cos(x)-1 + (x^2)/2 ) / (x^4 + y^4) (x,y) - (0,0) To evaluate this limit do i use L'Hospital's rule a few times to get it down to a solution or am i reading into it too much and is easier way? Cheers

Cheers First approach (0,0) from different directions. Along the y axis (x=0) then . Then along the x axis (y=0) then (use L'Hopital's rule on this one)
