Hello, my name is Yadira and my question is how is trigonometry applied to everyday lives and functions. Ex: Builders use it but how and what are some examples of the trig-functions or formulas that they use? Thank you for taking the time to read and answer this!


Hi Yadira,

Just this morning I answered a question from Ben who wanted to know the area of a lot with 5 sides. To find the area I used the Law of Cosines.

Here are a few more examples of questions we have been asked where the answer involved the use of a trig function.

A wishing well
A 6 sided (hexagonal) pyramid
A geometry problem
The size of a lot
A 3 dimensional 5 pointed star This one is my favorite.The question comes from an artist who works with metal.
