Mathematically, such objects are described as exhibiting rotational symmetry, for being “invariant under rotation.” Such objects have a point (in 2-D) or an axis (in 3-D) about which an object ...

This jingle has helped generations of algebra students recall the quadratic formula that solves every equation of the form $latex ax^2+bx+c=0$. The formula is as ...

In the mathematical sense, an object has rotational symmetry if there is an axis around which you can spin it so that at the end of a less-than-complete rotation, it looks just the same as it did ...

For the parabola \(y=(x+6)(x-4)\) determine the coordinates and nature of its turning pont and the equation of the axis of symmetry. The roots are \(x=-6\) and \(x=4\). The aixs of the symmetry is ...
