Real Life Trigonometry
Trigonometry, as defined by Merriam-Webster, is  'the study of the properties of triangles and trigonometric functions and of their applications'. Trigonometry is one of the branches of mathematical and geometrical reasoning that studies triangles, particularly right triangles. Trigonometry uses the fact that the ratios of pairs of sides of triangles are functions of the angles. The basis for measuring triangles is the right-angled triangle. The term trigonometry means the measurement of triangles. Trigonometry is a branch of mathematics that developed from simple measurements. The word trigonometry comes from the Greek words trigonon, which means triangle, and metron, which means measure. Once this known, it is easy to understand some of the real life uses of trigonometry.

Let’s explore ways in which this science finds use in our daily activities. One use of trigonometry is the calculation of the height of waves in the ocean, which is of interest to oceanographers. It is also used to measure the distance between planets, which helps NASA know how far away other planets are and study their orbits. It is also used in navigation to calculate the distance to the shore from a particular point in the ocean, which helps naval and aviation industries, cruise captains, and everyday sailors. Architects also use trigonometry to measure the slope of a roof and to properly calculate structural load, which trickles down to use for construction workers who built the houses lived in today. Those are the scientific applications of the concepts in trigonometry, but most of the math we study seems to have little real-life application. So how much do we use trigonometry in everyday life? The answer is a lot. One of the biggest ways worldwide is music. Sound travels in waves, and this pattern, though not as regular as a sine or cosine function, is still useful in developing computer music. This means that sound engineers and technologists who research...
