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.
You can solve for sin18 by making use of trigonometry.
how can trigonometry use in metallurgy
One example of an astronomer's use of trigonometry is determining the distance to a star by triangulation.
Well, if Edward Cullen the bloodsucking vampire can use trigonometry. Then I am asuming farmers can as well.
Mechanics use trigonometry to find angles mostly used in body or chassis work.
The first recorded use of trigonometry came from the Hellenistic mathematician Hipparchus
yes they do
An architect who designs a bridge would use trigonometry, among other mathematical techniques.
None. You do not need any knowedge of astronomy to study and be an expert at trigonometry.
They use it to measure angles and lengths
