Engineers and Physicists use trigonometry, as well as people whose carrers involve acoustics, optics, and waves.
how can trigonometry use in metallurgy
Yes, because all sound waves can be modelled as sine (or cosine) waves, or combinations of sine waves.
That depends on your profession. If you are a math teacher, then you might use a lot of Trig. If you are an engineer, working with forces on any object from different directions, then you would use trig. Electrical engineers use trig. Surveyors use trig.
Engineers use trigonometry anywhere that involves non-right angles. That includes building cars and buildings, bridges, and many other structures. they also use trigonometry when dealing with fields, like magnetic and electric fields. Also, trigonometry is very important with engineers who deal with waves, such as sound or light engineers.
Yes.

I assume the question means "Do sound engineers make use of trigonometric functions?" There are at least two ways that sound engineers might make use of trig functions. The first way is directly. Speakers have limited angles of coverage. Also distances from speakers to various parts of the audience have to be known, as sound takes time to travel, and gets softer with greater distance. Since speakers are often up on tall towers, this is a 3D problem, and trigonometry may come into it. More fundamentally, but more indirectly, sound can be considered as a sum of sine waves, each with its own frequency, amplitude and phase. The various pieces of equipment used by sound engineers affect the amplitudes and phases of the various components of the sound. Phase can be particularly troublesome: because of the limited angle of coverage of an individual speaker, multiple speakers have to be used, and in the places where their coverages overlap, differences in phase can cause bad effects. Sound engineers have to understand all this. Disclaimer: I'm not a sound engineer.

One example of an astronomer's use of trigonometry is determining the distance to a star by triangulation.
