We lost the hour last night. That’s not a complete explanation for why the blog is later than usual this morning, but it’s part of it. I can’t tell you exactly how much, because I’m not a ...

In this video playlist, I show you how to solve different math problems for Algebra, Geometry, Algebra 2, and Pre-Calculus. The video will provide you with math help using step-by-step instruction.

Learn how to determine the magnitude and direction of a vector. The magnitude of a vector is the length of the vector. The magnitude of a vector is obtained by taking the square root of the sum of the ...

Abstract: This technical note is concerned with exponential stability analysis of linear time-varying systems represented by the second-order vector differential equations with the singular leading ...

Abstract: Is it possible to find the sparsest vector (direction) in a generic subspace S ⊆ ℝ p with dim(S) = n ; p? This problem can be considered a homogeneous variant of the sparse recovery problem ...

Among other things, the course includes elementary linear algebra, the solution of equation systems, the theory of functions of several variables, including both unconstrained and constrained ...

Note that all forces on the system act at the fixed point O. What does this say about the angular momentum of the system about point O? Also, consider the work/energy equation for the system.
