Functions to computer intersections between lines, find the distance between a point and a line, find the segment of a line inside a rectangle, intersect rectangles, intersect a circle with a rectangle, find if a point is inside a rectangle or circle, or find the angular radius of a circle...
Geometry: Geometries like Point, Line, Polygon, Circle, Triangle, SphericalTriangle, etc with specific functionalities and methods are implemented. Polynomial functions: Solve and find roots of a function to any degree (including Linear, Quadratic, Cubic, Quartic etc). Roman numerals: Convert roman ...
The radius of the circle is r = st, and its area is a = πr 2 = π(st)2. To make this look like a polynomial, we have to rewrite it as a = (πs2)t2. The derivative is a˙ = (πs2)(2t) a˙ = (2πs2)t The units of s are km/year, so squar- ing it gives km2...
"i had been struggling with the unit circle, essentially trying to learn it out of the textbook," brannan wrote. "i watched your videos and it all clicked." in 2009, khan decided to turn his hobby into a full-time job. he formed a nonprofit and got a small donation from ann doerr,...
Function A function from a set D to a set R is a rule that assigns a unique element in R to each element in D. In this definition, D is the domain of the function and R is a set containing the range. Which of these is a function???

If you take two complex numbers z1 and z2 on the unit circle and multiply them, you will get a third complex number z3, also on the unit circle. Treating the complex plane as a 2D normed vector space, you can define the angle each number makes with the x-axis. What you w...
