# Linear Algebra Formulas & Equations: With Examples - Bokus

Course syllabus - Uppsala University, Sweden

This form is sometimes called the standard form of a linear equation. Example: y = 2x + 1 is a linear equation: The graph of y = 2x+1 is a straight line . When x increases, y increases twice as fast, so we need 2x; When x is 0, y is already 1. So +1 is also needed; And so: y = 2x + 1; Here are some example values: Here is the formula for the random effects estimator (from Chapter 10 in Wooldridge): where and and the j's are vectors of 1's. The fixed effects estimator is: where F and g are time-demeaned matrices: and where which (according to Wooldridge, and comically in my opinion) is "easily seen to be a TxT symmetric, idempotent matrix with rank T-1." There are several different formulas for the equation of a line. Each Formula is explained in brief below. Click on any of the links to learn more about any of the different formulas.

linear algebra is often the first actual math course that students ever take up. It is a considerable change of pace from the regular high school mathematics and calculus, therefore, can be difficult for new students.

More advanced applications are ubiquitous, in areas as diverse as abstract algebra and functional analysis. Linear equations, formulas, links, video tutorials and much more matrix Xin the equation XA= B, multiply both sides of the equation by A 1 from the right: X= BA 1. To solve for Xin ABCXD= E, multiply both sides of the equation by D 1on the right and by A , B 1 and C 1(in that order) from the left: X= C 1B A 1ED . III. COMPUTATIONAL LINEAR ALGEBRA Okay, I hear what you are saying “Dude, enough with the theory talk, let’s Sometimes a linear equation is written as a function, with f (x) instead of y: y = 2x − 3. f (x) = 2x − 3. These are the same! And functions are not always written using f (x): y = 2x − 3.
