sign. It is merely a scalar expression of the two variables mu and sigma. If you want to solve the equation "expression = 0", there will be a curve of solutions in the mu, sigma plane. If you look at the expression, you'll see that it is a quadratic equation in mu, which means that you could solve it explicitly and give mu as a function of sigma.
hi,
Actually it is equation only, while taking screen crop i missed that, here challenging is two variables are in list[],while passing them, i am getting error,
