Study Notes
Trigonometry is a branch of mathematics dealing with relationships between angles in triangles. It's often used to solve math problems involving circles such as finding angles in shapes and calculating distances using properties of geometrical figures. In addition, trigonometry can also help us understand the relationship between two sides of any triangle, which makes it useful when studying other branches of geometry like Euclidean Geometry. There are several key concepts within trigonometry including sine, cosine, tangent functions; Pythagorean theorem; lengths of segments of a circle; areas related to a given radius; chords; arcs; sectors; central angles; inscribed angles; radii; diameters; arcs; chords; inscribed angles; central angles; radii; diameters; arcs; chords; inscribed angle; central angle; radius; diameter; arc segment(arc), center point etc. Trigonometric functions such as sine, cosine, tangent, cosecant, secant, and cotangent have standard values. The most important thing to remember from this unit is that sines and cosines represent the ratio of opposite side over hypotenuse and adjacent side over hypotenuse respectively.
