2nd Order differential equation, numerical method
I've attached the question.
u=y and v=y′
let y'=dy/dt = du/dt = v
dv/dt = u''
therefore, dv/dt + 7(v)^2 +3x^2 *y^3 = 2
dv/dt = 2 - (7(v)^2) - (3x^2)*(u^3)
and dx/dt = 1, where x(t0)=0
and u(t0)=4, v(t0)=8
the only part I am not sure is the part I've bolded. i think x(t0)=0 however in all the other options it has x(t0)=1 so I am pretty much only left with the "none of these" option.
