From the series:Differential Equations and Linear Algebra Gilbert Strang, Massachusetts Institute of Technology (MIT) Solutions to second order equations can approach infinity or zero. Saddle points contain a positive and also a negative exponent or eigenvalue. ...
From the series:Differential Equations and Linear Algebra Gilbert Strang, Massachusetts Institute of Technology (MIT) Imaginary exponents with pure oscillation provide a “center” in the phase plane. The point(y, dy/dt)travels forever around an ellipse. ...
pictures and ellipse equations and pictures. I also used it to clear my concepts in topics such as multiplying matrices and quadratic formula. If you are don’t have much time, then I would highly recommend this software, and well even if you have a lot of time in hand, I still would...
We show that the free equations of motion reduce to the usual Chern-Simons equations proving on-shell equivalence between the formulations at different pictures of the same theory. Finally, we discuss the interaction terms. They require a suitable definition in order to take into account the ...
Although a few use other means (cf., Hall et al., 1989), most find this problem difficult without the use of algebraic equations. In other words, this is arguably an algebra problem that we might expect to be out of reach of students without algebr 展开 ...

A logarithm is a mathematical term that can also mean “exponent.” As a basic algebraic concept, it is important to understand how to compute logarithms for nearly any math class that involves advanced algebra. Possibly because the wording of logarithm problems is somewhat topsy-turvy, this part...
a number of methods for solving simultaneous equations may be applied. Linear algebra techniques or solving by use of computer software are some of the more common techniques used. An interpolated y value on a quadratic spline is found by using the general quadratic equation, y = a*x2+ b*...
allows us to see that two of the smaller number, added to the difference (8), will give us the sum of the two numbers (20). After the model is set up, it functions as a bridge to algebra. A blue block can be labeledb, and from there, we can write equations to express what is...
