This program parses a mathematical expression into a syntax tree. Below is an example of a syntax tree for expression 2xsin(x - 1) + ln(x + 2) generated with graphviz.

Abstract: Finding the inverse z-transform of a rational function is usually considered a completely routine task with nothing special to say about it. However, practically all the procedures described ...

The convolution of two rational transfer functions is also rational, but a formula for the convolution has never been derived. This paper introduces a formula for the convolution of two rational ...

It’s been a hard couple of years, so maybe 2022 isn’t the year for grand, difficult goals. Many of us are simply too worn down from uncertainty and loss to dream of big business plays, complete ...

Using high school algebra and geometry, and knowing just one rational point on a circle or elliptic curve, we can locate infinitely many others. You’re sitting at the end of a long conference table, ...

With views of the water, skyline, bridges and piers, the promenade encapsulates New York’s history. Our critic walks with the architect Deborah Berke. Credit...Vincent Tullo for The New York Times ...

A major use in defining functions is for using them to define further functions. This would be useful for visualising, explaining and manipulating composite functions, a major concept in mathematics ...

When I ask leaders and teams to concisely summarize their company’s management approach, the pause I get hangs in the air like a frisbee tossed on a windy day. No one seems to know which direction the ...
