Let f(x;y) = sin(x2 y2) x2 y2 Then nd lim (x;y)!(0;0) f(x;y) Solution We can compute the limit as follows Let r2 = x2 y2 Then along any path r(t) = hx(t);y(t)isuch that as t !1, r(t) !0, we have that r2 = krk2!0 It follows that lim (x;y)!(0;0) f(x;y) = lim r2!0 sinr2 r2 = lim u!0 sinu u = 1 A Havens Limits and Continuity for, ,c w xyz x t y t z t= = = = sin sin ; Find the limit using the polar coordinates `x=rcos(theta)` , `y=rsin(theta)` , `r=sqrt(x^2y^2)` ` lim_(x,y>0,0) (x^2*y^2)/sqrt(x^2y^2)` We must know that r is approaching 0 from the right when

1 Stewart 5 pts Find the limit or say why it does not exist lim (x;y)!(0;0) x2 sin2 y x2 2y2 Solution The limit is equal to zero To see this, use the Squeeze Theorem Since x 2 x 2y2, we have x2 x22y2 1, therefore 0 2 x2 sin y x2 2y2 sin2 y Since sin2 y goes to zero as x;y go to zero, the middle term does also 2 Stewart 14Log in here We have to find lim (x,y)> (0,0) sin (x^2y^2)/ (x^2y^2) Let x^2 y^2 = t => Substituting t = 0 gives 0/0 which is indeterminate Use l'Hopital's rule and substitute sin t andI Limits in y 0 6 y 6 √ 4 − x2, so the positive side of the disk x2 y2 6 4 I Limits in z 0 6 z 6 p 4 − x2 − y2, so a positive quarter of the ball x2 y2 z2 6 4 2 z x y 2 2 Triple integral in spherical coordinates Example Change to spherical coordinates and compute the integral I = Z 2 −2 Z √ 4−x2 0 Z √ 4−x2−y2 0 y p
