Homework Help: Math

Posted by Alice on Sunday, May 17, 2009 at 5:29am.

A set of homogeneous simultaneous equations is given by
x + ky = 0
kx + 3y = 0
Calculate the two values of k that lead to non-trivial solutions to these
equations and express y in terms of x for the two values.

I thought that for the solutions to be no trivial the determinant of the coefficients had to equal zero. From this I got k=+/- sqrt 3 but I am not sure of this is right.
