Līlāvatī

Līlāvatī is a treatise by Indian mathematician Bhāskara II on mathematics, written in 1150 AD.

[2] Bhaskara II's book on arithmetic is the subject of interesting legends that assert that it was written for his daughter, Lilavati.

The auspicious moment for the wedding thus passed unnoticed leaving Bhaskara II devastated.

Thus, he promised his daughter to write a book in her name, one that would remain till the end of time as a good name is akin to a second life.

The book contains thirteen chapters, mainly definitions, arithmetical terms, interest computation, arithmetical and geometrical progressions, plane geometry, solid geometry, the shadow of the gnomon, the Kuṭṭaka - a method to solve indeterminate equations, and combinations.
