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.

If you have read Neal Stephenson’s Quicksilver—the first volume of his Baroque Cycle (2003)—you will remember the smell of the age he recreates: Wet ink, gossip, gunpowder, and the new arrogance of ...

A major global study suggests that a hidden mismatch between two common blood tests could quietly signal serious trouble ahead. When results from creatinine and cystatin C—two markers used to assess ...

Abstract: We introduce a method for proving almost sure termination in the context of lambda calculus with continuous random sampling and explicit recursion, based on ranking supermartingales. This ...

Have you ever found yourself frustrated with an Excel workbook that seems to lag, break, or throw errors at the worst possible time? If so, there’s a good chance the culprit is one of Excel’s most ...

Many people with multiple sclerosis (MS) expect to cope with physical challenges like problems with walking or seeing, but the disease's central nervous system damage often causes mental health ...

Almost half of everyone who lives in the United States breathes unhealthy levels of air pollution, according to the American Lung Association’s annual State of the Air report, released Wednesday.

IN the second volume of his large treatise on the integral calculus, Mr. Edwards deals with multiple integrals, gamma functions, Dirichlet integrals, definite integrals in general, contour integration ...

Health screenings, like those for colorectal cancer, can uncover issues at an early stage—when they may be more treatable. But as we get older, it’s not always clear which tests are still essential.

Abstract: Numerous tasks in imaging and vision can be formulated as variational problems over vector-valued maps. We approach the relaxation and convexification of such vectorial variational problems ...
