I have to study the solutions of the following system of three equations and three unknowns upon variation of parameters k and h. ix1+kx2-x3 = 1+i (k+i)x1+(1-i)x2-(ik-1)x3 = h kx1+(4+2i)x2-(k-3-3i)x3 = 1-i Obviously i is the imaginary unit. And as stated k and h are the parameters . I can't...

I see, thank you!

Either because of biological hard wiring or/and societal conditioning, people will prefer certain things over others. And this includes the characteristics that they would like in a potential lover. Since both looks and personality are just characteristics (even though the latter is generally...

Homework Statement Consider the following incorrect theorem: ∃x∈ℝ ∀y∈ℝ (xy^2 = y-x) [Translation (not part of the original problem statement): There is at least an x∈ℝ such that, for every y∈ℝ, (xy^2 = y-x).] What's wrong with the following proof? Let x = y(y^2+1), then...

I figured that i can get (and give) some help with homework, plus having all kinds of interesting discussions, in this forum. So here i am. Hi to everyone.
