Natural Trigonometric Functions

Sine, Cosine and Tangent - Natural Trigonometric Functions

Sponsored Links

Natural trigonometric functions are expressed as

sin θ = cos (π / 2 - θ) (1)

cos θ = cos (π / 2 - θ) (2)

tan θ = sin θ / cos θ = 1 / cot θ = cot (π / 2 - θ) (3)

cot = 1 / tan θ = cos θ / sin θ = tan(π / 2 - θ) (4)

Trigonometric functions ranging 0 to 90 degrees are tabulated below:
