2020年11月28日 · The {a = 0.6, b = 0.3} controls the direction of the tower, while the expression 0.04/t^2 (1 - t) + t (1 - t) controls the radius. Here's why I chose this specific expression for the radius: When t is near zero the radius behaves as 0.04/t^2 so you get infinitely large circles creating an infinitely large base shrinking to form a nice smooth join with the tower.
2019年9月12日 · It’s built on a huge tower of technology, but what it does is to let any student—without learning any syntax or reading any documentation—immediately build up or work through computations. *Just type input the way you would in Wolfram|Alpha. But now you’re.

2013年1月1日 · There are many approaches to domain coloring. The approach in @cormullion's answer is to use Re and Im as the mesh functions. Another way is to color points just by Arg(f(z)) Arg (f (z)) and then superimpose contours for Abs(f(z)) Abs (f (z)).

Therefore, any package of financial instruments that has the same future cashflows as a certain bond must have the same price as that bond. Mathematica makes it relatively easy to learn about bond pricing and the surprisingly many and more subtle related concepts of duration, curvature, yield to maturity, etc. 1a.
