Definition: A circle with a radius of 1 centered at the origin of a coordinate plane.
Angles: Angles are measured counterclockwise from the positive x-axis.
Coordinates: The x-coordinate represents the cosine of the angle, and the y-coordinate represents the sine of the angle.

Understanding the unit circle is crucial for grasping the periodic nature of trigonometric functions. LEARNS.EDU.VN offers interactive unit circle tutorials to enhance your understanding.

3.3. Trigonometric Identities

Trigonometric identities are equations that are true for all values of the variables.

Pythagorean Identities: sin²θ + cos²θ = 1, 1 + tan²θ = sec²θ, 1 + cot²θ = csc²θ
Reciprocal Identities: csc θ = 1/sin θ, sec θ = 1/cos θ, cot θ = 1/tan θ
Quotient Identities: tan θ = sin θ/cos θ, cot θ = cos θ/sin θ
Angle Sum and Difference Identities: sin(A ± B), cos(A ± B), tan(A ± B)
Double Angle Identities: sin(2θ), cos(2θ), tan(2θ)

Mastering these identities is essential for simplifying trigonometric expressions and solving equations.

Cosine Function (y = cos x): Periodic with a period of 2π, amplitude of 1, and oscillates between -1 and 1. It is a horizontal shift of the sine function.
Tangent Function (y = tan x): Periodic with a period of π, has vertical asymptotes, and ranges from -∞ to ∞.

Graphs of trigonometric functions visually represent their periodic nature and behavior over different intervals.

3.5. Inverse Trigonometric Functions

Inverse trigonometric functions find the angle given a trigonometric ratio.

Arcsine (sin⁻¹ or arcsin): Returns the angle whose sine is a given value.
Arccosine (cos⁻¹ or arccos): Returns the angle whose cosine is a given value.
Arctangent (tan⁻¹ or arctan): Returns the angle whose tangent is a given value.

Inverse trigonometric functions are essential for solving equations where the angle is unknown.
