Question 334075: I was wondering what trigonometry is used for? and at what age should it be best learned
Answer by jrfrunner(365)   (Show Source):
You can put this solution on YOUR website! trigonometry is used to measure lengths of buildings, angles, figure out areas of shapes, volumes of shapes, basically to measure many physical properties of objects around us. It is used by mechanical engineers, people working in construction and manufacturing, etc.

It should probably be learned at an early age, but I would say around 13-14 is a good age, though the earlier the better.
