different angles so that they can be heard Engineers use trigonometry in Concert areas, rooms or other places that are made for the production and use of music so that the sounds are transferred and bounce off of the walls to make the sounds balanced and easy to hear. Trigonometry is used in measuring the level or pitch of a sound wave or musical note. These notes are measured in hertz. People can use panels in rooms such as studios and turn them in different angles so that the music waves bounce off just right to make the song sound smooth and even. In the following equation which is used to describe the mathematical part to the use of a microphone (t) is time, (A) is amplitude, and (w) is frequency.

f(t) = A sin(2 pi w t)
