Jakub Nakcjanowicz or Nakcyanowicz (Lithuanian: Jokūbas Nakcijonavičius; 1 May 1725 – 1777) was a Jesuit priest, mathematician, and astronomer of the Polish–Lithuanian Commonwealth.
[2] In the university itself, Nakcyanowicz lectured on mathematics, geodesics, philosophy, and experimental physics.
Nakcyanowicz developed a mathematics textbook entitled Exercitationes in analysi cum finitorum tum infinitorum mathematicae, which was published in 1758.
He wrote another textbook entitled Praelectiones mathematicae ex Wolfianis elementis adornatae in 1759–1761, which concerned the basic principles of mathematics, arithmetic, geometry, trigonometry, and some algebra.
In 1762 published a work on conic sections and other algebraic and transcendental curves.
