 2d awarded Popular Question Apr22 comment Diagonal decomposition, square root and eigenvector / eigenvalue of a matrix assuming this matrix is even diagonalizable, to get $V$ and $D$ you need to already know the eigenvalues and eigenvectors, or you could just find $V$ and $D$ using computational software, otherwise I would suggest doing $Det(\lambda I - A)$ and seeing if you can factor the cubic.

Apr21 comment Math: A discovery or a creation? a discovery -plato Apr17 comment Uniformly distributed independent random Variables make a double integral $\int\int f(x)g(y)dxdy$ what are the bounds? what is $f(x)$ and $g(y)$? I suppose you'll need to use the fact that $P(a|b) = P(a,b)/P(b)$ as well Mar31 comment What is the $x$-intercept for $\frac{2x^2}{x^2-1} = 0$ no, I'm referring to multiplying both sides by the denominator of the fraction $x^2 + 1$ Mar31 comment What is the $x$-intercept for $\frac{2x^2}{x^2-1} = 0$ clearing denominators is a common theme in algebraic simplification Mar31 comment What is the $x$-intercept for $\frac{2x^2}{x^2-1} = 0$ because you can just multiply both sides by the denominator and it disappears. Mar31 comment What is the $x$-intercept for $\frac{2x^2}{x^2-1} = 0$ what you have in your title is the equation you need to solve to find the x-intercepts, so just solve that equation, and you'll have them.
