Bartholomaeus Pitiscus is best known for his book called Trigonometria which was first published in Heidelburg in 1595. It consists of work on plane and spherical trigonometry. The book had the first recorded mention of the word "trigonometry".
Created the division of a circle into 360 degrees and made one of the first trigonometric tables for solving triangles.
how can trigonometry use in metallurgy
Trigonometry is used effectively in electronics.
I can give you several sentences.I have to take trigonometry next year.Trigonometry relates to triangles.I never did understand how to do that trigonometry problem.
Trigonometry originated in ancient times, and was closely related to geometry. It was useful especially in astronomy and navigation. Later on trigonometry led to the idea of sine waves as fundamental for analysing vibrations of all kinds. Trigonometric functions occur in the theory of complex numbers, and now the trig functions turn up in many places in mathematics and its applications, from optics to the theory of alternating current in electrical engineering. The uses of the trig functions have spread far beyond the original ones.

Several great mathematicians have made contributions to trigonometry. Pitiscus wrote books on plane and spherical trigonometry, and Hipparchus produced a table of chords.
