Learn how to solve complex engineering mechanics problems using Python 3 and the industry's best practices.

📖 Build your own frontend framework

You can now purchase my new book: Build a frontend framework (from scratch). In this book, I teach you how to build your own frontend framework, line by line, so that you can learn how they work internally.

📖 Solve engineering problems using Python

I wrote a book for engineering students (with a background in mechanics) to learn how to write Python programs to solve complex engineering problems. You can check out all the details in the book's website. You can already buy it from No Starch Press and Amazon.

The source code for the book is open source and you can find it in my Mechanics repository.

If you read it and you liked it, I'd love if you could write me a nice review in Amazon. Thanks!

self.u * sin - self.v * cos

The second sign should be a + instead of -.

Contains point

Hi,

I am working through your book and enjoying it so far. Well written and reminding me of all the things I learnt during my engineering degree. When writing tests for the contains_point function for a generic polygon using winding number algorithm the algorithm seems to fail when a square/rectangle is entered as a polygon. Is this to be expected? In my mind it should work but I cant figure out why it doesn't unless an absolute value is generated from the angle sum.
