Solve the differential equation $$y'=y^2-x$$ with two different initial conditions: $y(0)= 1$ and $y(0)=0.5$. My idea: Suppose $y^2=t$ then $2yy'=t' \Rightarrow y'= \frac{t'}{2 \sqrt{t}}$ 2020-07-19 2016-07-08 xdy= (y+x^2+y^2) dx xdy-ydx =(x^2+y^2) dx -xdy+ydx =-(x^2+y^2) dx ydx -xdy=-(x^2+y^2) dx (ydx -xdy)/y^2=-((x/y)^2+1) dx d(x/y)= -((x/y)^2+1) dx if z=x/y d(z)= -((z)^2 2005-01-24 The first differential equation has no solution, since non realvalued function y = y (x) can satisfy (y ′) 2 = − x 2 (because squares of real‐valued functions can't be negative). The second differential equation states that the sum of two squares is equal to 0, so both y ′ and y must be identically 0. Simplify the expression \frac{1}{y-y^2}dy.
