(-1)^4*xdx + (8y-y^2-13)dy=0; y(0)=4;
1. Use dsolve to obtain a solution.
2. As dsolve was not much help find an implicit solution of the form
f(x, y) = 4
The Attempt at a Solution
the dsolve part was easy, i just did:
syms x y t
and got a huge matrix-type answer.
So now, i'm having some trouble with 2. My prof told us to use ode45, and this is what i'm thinking:
[x,y]=ode45(Z, -10:10, 4)
but i'm getting some errors that its not a proper function name, and some stuff with feval.
Is the problem with the Dy and Dx? My prof suggested using inline, but i read that its older syntax that doesn't really help much, according to mathworks :/
Any suggestions? thanks!
