WebStep 2: Express the function in spherical coordinates. Next, we convert the function. f (x, y, z) = x + 2y + 3z f (x,y,z) = x + 2y + 3z. into spherical coordinates. To do this, we use the conversions for each individual cartesian coordinate. WebJan 23, 2024 · The first integral vanishes (because it integrates to the constant $\sqrt{2\pi}$) and the second integral is what you wanted: an integral over the logistic function "in a univariate Gaussian expectation".
