Graphs of quadratic functions can be used to solve equations. Example Draw the graph of y = 2 x 2 + 2 x 4 for values of –3 to 2. Use the graph to solve the equation y = 2 x 2 + 2 x 4. Solution ...

It is shown that for wave functions of the form Ψ = Σk Ck exp (-Qk), where Qk is any positive definite quadratic form in the Cartesian co-ordinates of n particles and Ck a constant, all integrals ...
