First we need to complete the square to get the coordinates of the turning point. \(y = {x^2} + 2x + 3\) \(y = {(x + 1)^2} - 1 + 3\) \(y = {(x + 1)^2} + 2\) Therefore the coordinates of the turning ...

The women behind "Moebius Noodles: Adventurous Math for the Playground Crowd" are back with another fun math game they call Function Machines. I introduced Maria Droujkova and Yelena McManaman last ...

Mathematicians used “magic functions” to prove that two highly symmetric lattices solve a myriad of problems in eight- and 24-dimensional space. The points could be an infinite collection of electrons ...

Amid the chaos of revolutionary France, one man’s mathematical obsession gave way to a calculation that now underpins much of mathematics and physics. The calculation, called the Fourier transform, ...

“Suppose f is a quadratic function satisfying f(6)=0, f(-6)=0, and f(0)=10. Then f(4)= A. 5 B. 5.5 C. 5.555 D. 5.666 E. None of the above. “OK, come on up here to the board and do those computations ...
