📐 TRIGONOMETRIC FUNCTIONS — OVERVIEW

There are 6 fundamental trigonometric functions, each describing a specific ratio between the sides of a right triangle or coordinates on the unit circle.

sin(θ) = opposite / hypotenuse = y-coordinate on unit circle

cos(θ) = adjacent / hypotenuse = x-coordinate on unit circle

tan(θ) = opposite / adjacent = sin(θ) / cos(θ)

csc(θ) = hypotenuse / opposite = 1 / sin(θ)

sec(θ) = hypotenuse / adjacent = 1 / cos(θ)

cot(θ) = adjacent / opposite = 1 / tan(θ) = cos(θ) / sin(θ)

📊 SIGNS BY QUADRANT

Quadrant I (0°–90°): All functions positive — sin+, cos+, tan+

Quadrant II (90°–180°): sin+, cos−, tan− (mnemonic: "Silver")

Quadrant III (180°–270°): sin−, cos−, tan+ (mnemonic: "Tarnished")

Quadrant IV (270°–360°): sin−, cos+, tan− (mnemonic: "Copper")

ASTC (All Students Take Calculus): Remembers which functions are positive in each quadrant.

📋 KEY IDENTITIES

Pythagorean: sin²θ + cos²θ = 1 | 1 + tan²θ = sec²θ | 1 + cot²θ = csc²θ

Periods: sin, cos, csc, sec have period 360° (2π). tan, cot have period 180° (π).

Even/Odd: cos and sec are even (f(−θ)=f(θ)). sin, tan, csc, cot are odd (f(−θ)=−f(θ)).

Co-function: sin(θ) = cos(90°−θ), tan(θ) = cot(90°−θ), sec(θ) = csc(90°−θ).

⚠️ UNDEFINED VALUES

sin = 0, csc undefined: at θ = 0°, 180°, 360°, ...

cos = 0, sec, tan undefined: at θ = 90°, 270°, ...

tan = 0, cot undefined: at θ = 0°, 180°, 360°, ...
