Thread: dy/dx=x^2y-y^2+2x

Here's the problem:

the solution to y0 is dy/dx=x^2y-y^2+2x; and y(-2)=3-- now we are also told that y'0(-2)=1 now for the part im having trouble with: find y''0(-2)
now from the problem i was thinking to take the derivative of the equation they gave me... so that would mean implicit differentiation??: 2xy+x^2y'-2yy'+2... but when i plug in -2 for x and 3?? for y i get -5... any help is appreciated ty (Nod)

Hi





You need to plug in -2 for x, 3 for y0(-2) and 1 for y0'(-2)

Hey, thanks for reply. Ok it hadn't occured to me about plugging in 1 for y'. I also realized I made a typo since it was supposed to be y0'(-2)=-1 which comes out to be -8 instead of -12 of what I was getting when I plugged in 1. Thanks again lol
