I have just started a pre calculus class, and our first lessons have been reviews on polynomial equation, quadratics and finding roots or solutions to equ...

Where $n \in \mathbb{R}$ and $m \in \mathbb{R}$, what is the function $f(n, m)$ that can achieve rounding behavior of money where the smallest denominatio...

I wonder why The complete bipartite graph K2,5 is planar?

From my understanding from university physics from Pearson (Page ~20): Dot product multiplies "like" unit vector terms and cross product multiplies "unlik...

We may start with this definition of the circle: The set of all points in the plane that are at equal distance (different from $0$) from some fixed point ...

I trying to scale object up and back down, I can only use a scale factor to alter the size. I am currently scaling upwards by 1.2. How do I calculate the ...

Intuitively, $\lim\limits_{t\to -\infty}te^t=0$, since $e^t\to 0$ much faster than $t\to -\infty$. Is there a way to more rigorously compute this? Writing...

I'm struggling with this assigment and I need some tips/hints to solve this. In a field there is the additional requirement that $0\ne1$, hence a fie...

I know how to derive the equation for finding arc length in polar coordinates but I don't understand this: Given a parametric equation let L be the l...

My 6 year old wants to know if infinity is an odd or even number. His 38 year old father is keen to know too.
