Solution: det (A) = −5, and for n×n matrix adj (A) has determinant (det A)^ (n−1). Here n = 3, so det (B) = (−5)^ (2) = 25. For feedback or story ideas, reach us at [email protected] ...

Cybercriminals have a new, user-friendly tool for turning your browser alerts into a vector for phishing attacks. "Matrix Push" is slick, it's pretty, and it's about as easy to use as any commercial ...

You'll be more productive if you can see what you need to do, and when you need to do it. This assessment and productivity tool is named for former president Dwight Eisenhower, who once quoted Dr. J.

Abstract: A mobile robotic measurement system combined with a mobile tracker (MRSMT) provides a promising solution for 3-D full-field measurement because the measurement range can be flexibly enlarged ...
