21 hours ago · In general, in a Cartesian coordinate system x i on a Euclidean space, the partial derivatives ∂ / ∂x i are orthonormal with respect to the Euclidean metric. Thus the metric tensor is the Kronecker delta δ ij in this coordinate system. The metric tensor with respect to arbitrary (possibly curvilinear) coordinates q i is given by

Also shown are: semi-major axis a, semi-minor axis b and semi-latus rectum p; center of ellipse and its two foci marked by large dots. For θ = 0°, r = r min and for θ = 180°, r = r max.
21 hours ago · Motivation H 1 does not separate the classes. H 2 does, but only with a small margin. H 3 separates them with the maximal margin. Classifying data is a common task in machine learning. Suppose some given data points each belong to one of two classes, and the goal is to decide which class a new data point will be in. In the case of support vector machines, a data point is viewed as a p ...
21 hours ago · where F is the repulsive force between two electrical charges, Q G 1 and Q G 2 are the two charges in question, and r is the distance separating them. If Q G 1 and Q G 2 are expressed in statC and r in centimetres, then the unit of F that is coherent with these units is the dyne.
