1 day ago · The normal vector is very important as it defines the equation for a plane, which is the set of points that have the same normal vector. Timestamps: Question 11: Find a vector perpendicular to a plane: 0:00. Solution: Find cross product of any 2 non-parallel vectors on the plane: 0:05. Find position vectors on the plane: 0:31
1 day ago · The normal distribution, also called the Gaussian distribution, is a probability distribution commonly used to model phenomena such as physical characteristics (e.g. height, weight, etc.) and test scores.
5 days ago · The normal distribution is a theoretical distribution of values for a population. Often referred to as a bell curve when plotted on a graph, data with a normal distribution tends to accumulate around a central value; the frequency of values above and below the center decline symmetrically.
5 days ago · In probability theory and statistics, the multivariate normal distribution, multivariate Gaussian distribution, or joint normal distribution is a generalization of the one-dimensional normal distribution to higher dimensions.

1 day ago · Probability theory. In probability theory and statistics, a normal distribution or Gaussian distribution is a type of continuous probability distribution for a real-valued random variable. The general form of its probability density function is The parameter is the mean or expectation of the distribution (and also its median and mode ), while ...
