"A degree (in full, a degree of arc, arc degree, or arcdegree), usually denoted by ° (the degree symbol), is a measurement of a plane angle..."
Units of measurement for angles.
Angle measurement: Understanding the concept of measuring angles and the different units of measurement such as degrees, radians, and revolutions.
Degree to radian conversion: Knowing the formulas to convert degrees to radians and vice versa.
Radian measure: Understanding how radian measure relates to the circumference and diameter of a circle and how to convert between radians and arc length.
Trigonometric functions: Learning about the six trigonometric functions (sine, cosine, tangent, cotangent, secant, and cosecant) and how they relate to angles in a right triangle.
Unit circle: Understanding the concept of the unit circle, its properties, and how it is used to define trigonometric functions for any angle.
Trigonometric identities: Learning about the different trigonometric identities such as Pythagorean, reciprocal, quotient, and co-function identities.
Angles of rotation: Understanding how to find the angle of rotation of a point on a coordinate plane and how it relates to the trigonometric functions.
Trigonometric equations: Learning how to solve trigonometric equations using algebraic techniques and the properties of trigonometric functions.
Inverse trigonometric functions: Understanding the inverse trigonometric functions (arcsine, arccosine, arctangent, arccotangent, arcsecant, and arccosecant) and how they relate to finding the angles in a right triangle.
Trigonometric applications: Understanding the practical applications of trigonometry such as solving problems related to height, distance, angles of elevation and depression, and navigation.
