Trigonometry

__**Trigonometry **__ Historically, trigonometry was developed for astronomy and geography, but scientists have been using it for centuries for other purposes as well. Besides mathematics, trigonometry is used in physics, engineering and chemistry. Within mathematics, trigonometry is primarily used in calculus, linear algebra and statistics.
