Okay, but the result of this equation is that y(t) is a complex function ( y² = sqrt(-(t²+1))/t ). Can this be the right answer?
How exactly do you separate?
I want to solve the following ODE:
(1 + t²)y' = ty(1 + y²) where y = y(t).
If I try to solve it by separation, I get complex roots, but I'm not trained yet to deal with them.
What should I do?
I'm glad I found this forum. I am being amazed by some topics in the "Dark Discussions at Cafe Infinity" section. Mainly one article about the Vandermonde Determinant.
Ah I got it, you start from the beggining, I was doing the cofactors of the last terms... Thank you!
Hello, I want to prove that the determinant of Fibonacci's nxn tridiagonal matrix is equal to the (n+1)th term of the Fibonacci sequence.
I'm trying to do it by induction, stating that det(F(n)) = det(F(n-1)) + det(F(n-2)) (yeah I don't know how to use LaTex)
but I don't know how to prove that the minor M(n, n-1)(F(n)) = det(F(n-2))
Thanks.
