There is no single law in trigonometry so the question makes no sense.
there many jobs that have to uses trigonometrysuch as a carpentry , law and order these jobs have to use trigonometry because for carpentry if you don't use it then you might as well not use it any ways and you Can also use it to impress the boss you know mabye get a little raise in your money but really when you are cutting out an angle you have to use trigonometry, also architecture uses trigonometry so they can figure out how to build the complex shapes that modern buildings require
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 is used in the design and construction of buildings, cars, planes, and many other objects. Trigonometry is used in physics and engineering whenever forces, waves, fields, and vectors are involved. Trigonometry is used in music and acoustics to design speakers, instruments, and concert halls. Trigonometry is used to coordinate launches OS space shuttles. Trigonometry is used to navigate ships and planes. Nearly every part of modern life uses trigonometry in some way.
plane trigonometry spherical trigonometry
The main kinds are plane trigonometry and solid trigonometry. The latter will include trigonometry in hyper-spaces.
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.
Trigonometry is applied in construction and building, as trigonometry measures right angled triangles.
Hipparchus is the father of trigonometry.

Trigonometry based on a unit circle and radians and trigonometry based on a right triangle.
