Fun fact: Did you know that the word "trigonometry" comes from the Greek words "trigonon" (triangle) and "metron" (measure)? So, trigonometry literally means "triangle measurement"!
Let's break down the core concepts within trigonometry:
Sine (sin): The ratio of the length of the side opposite the angle to the length of the hypotenuse.
Cosine (cos): The ratio of the length of the side adjacent to the angle to the length of the hypotenuse.
Tangent (tan): The ratio of the length of the side opposite the angle to the length of the side adjacent to the angle.
Angles of Elevation and Depression: These are angles formed between a horizontal line and a line of sight.
Bearings: A way of specifying direction, measured clockwise from North.
Interesting fact: The ancient Egyptians used trigonometry to build the pyramids! They needed to accurately calculate angles and distances to ensure that the pyramids were perfectly aligned.
Before you dive into studying, take some time to assess your current understanding of trigonometry.
