Discrete mathematics is the study of mathematical structures that are fundamentally discrete rather than continuous. In contrast to real numbers that have the property of varying "smoothly", the objects studied in discrete mathematics β such as integers, graphs, and statements in logic β do not vary smoothly in this way, but have distinct, separated values. Discrete mathematics therefore excludes topics in "continuous mathematics" such as calculus or Euclidean geometry. Discrete objects can often be enumerated by integers. More formally, discrete mathematics has been characterized as the branch...

So, I was trying to find the polar equation for a sine curve and here's what I did :
Now, some assumptions that I've made here are : $\theta\in\left(0,\dfrac\pi2\right)$ and $C_x<\pi$, where $C_x$ is the abscissa of $C$.
So, $\sin\theta=\dfrac{BC}{r}\implies BC=r\cdot\sin\theta$ and $\cos\theta=...
John Caldwell Holt (April 14, 1923 β September 14, 1985) was an American author and educator, a proponent of homeschooling and, specifically, the unschooling approach, and a pioneer in youth rights theory.
After a six-year stint teaching elementary school in the 1950s, Holt wrote the book How Children Fail (1964), which cataloged the problems he saw with the American school system. He followed it up with How Children Learn (1967). Both books were popular, and started Holt's career as a consultant to American schools. By the 1970s he decided he would try reforming the school system and began to...
