Applications of Trigonometry

 

 NASA uses it too!

es, they use trigonometry to calculate how far a planet or a star is from Earth. For example, to calculate the distance between the Earth and the moon, the circumference of the moon and one of the diameters are used to calculate the arc-length formula. Putting the values, the exact distance in the Miles unit comes out. Neil Armstrong and Edwin Aldrin successfully etched their name in history by landing on the moon only because trigonometry helped in all the calculations. 

Developing sound effects

Imagine you are watching a horror movie. When a spirit suddenly appears on the screen, you jump because of the scene and the eerie sound. Also, when you scroll through YouTube, you will find posts like “music for deep concentration, the study” or something like that. How do you think sound engineers develop these sound effects with the perfect pitch, volume, and other things? Yes, you got it right. They study the sound waves created by sine and cosine curves, analyze and comprehend the music and make necessary changes.
