Best ResponseYou've already chosen the best response.0Oohhhh... F... Okay, I'm glad I asked. I'm only in Trig. Coincidentally, my teacher was saying how important trig was for calc 2, but I'm skeptical I can be helpful.

Best ResponseYou've already chosen the best response.0well you know x=5 y=20 dx=.2 and dy=.4 differentiate z to get dz and then you can plug in the values of x,y,dx,dy resulting in dz

Best ResponseYou've already chosen the best response.0\[dz=[1/2(x^2y+xy^2)^{1/2}(2xy+y^2)]dx\] \[+ [1/2(x^2y+xy^2)^{1/2}(x^2+2xy)]\] \[x=5, dx=.2, y=20, dy=.4\] Plug these values in and let me know what you get

Best ResponseYou've already chosen the best response.0Here is the entire equation with any typos, sorry for the confusion \[dz=[1/2(x^2y+xy^2)^{−1/2}(2xy+y^2)]dx\] \[+[1/2(x^2y+xy^2)^{−1/2}(x^2+2xy)]dy\] \[x=5,dx=.2,y=20,dy=.4\]
