Ancient Egyptian and Babylonian mathematicians lacked the concept of an angle measure, but they studied the ratios of the sides of similar triangles and discovered some properties of these ratios. The ancient Nubians used a similar methodology.
It is a number - in trigonometry or elsewhere.
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.
I should imagine that his parents discovered him!
Trigonometry came first thousands of years ago. Calculus was only discovered several hundered years ago.
Benjamin Banneker discovered the Trigonometry Puzzle
Trigonometry has been developed over centuries, and was not discovered per-se by any one person. One might say that Pythagoras is the father of trigonometry because the Pythagorean theorem is so central to trigonometric theory, but many cultures were aware of the Pythagorean theorem before Pythagoras was even born.

The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.

TRIGONOMETRY
Hipparchus is the father of trigonometry.
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
Plane trigonometry is trigonometry carried out in (on) a plane. This could be contrasted with spherical trigonometry, which is trigonometry carried out on the surface of a sphere. Certainly there are some other more complex forms of trig.
