Re: [分析] 一題ode
※ 引述《Bourbaki (大狐狸)》之銘言：
: dx
: ---- = x(y^2 + 1)
: dt
: dy
: ---- = -y(x^2 + 1)
: dt
: 請問該怎麼解呢
: 謝謝^^
dy/dx=-y(x^2+1)/x(y^2+1), this is separable
but this only solve the solution curve in terms of x and y,
as for how to parameterize it? u can think about it.
at least one is the function of the other locally.
