Pythagorean Identities
sin 2 θ + cos 2 θ = 1 sin 2 θ + cos 2 θ = 1 1 + cot 2 θ = csc 2 θ 1 + cot 2 θ = csc 2 θ 1 + tan 2 θ = sec 2 θ 1 + tan 2 θ = sec 2 θ

### What are the all formulas of trigonometry?

Shifting angle by π/2, π, 3π/2 (Co-Function Identities or Periodicity Identities)

 sin (π/2 + x) = cos x cos (π/2 + x) = – sin x sin (3π/2 – x) = – cos x cos (3π/2 – x) = – sin x sin (3π/2 + x) = – cos x cos (3π/2 + x) = sin x sin (π – x) = sin x cos (π – x) = – cos x sin (π + x) = – sin x cos (π + x) = – cos x

#### What are the basic identities?

The basic trig identities or fundamental trigonometric identities are actually those trigonometric functions which are true each time for variables….Basic Trig Identities.

Basic Trig Identities
cot x = cos x/sin x Equation 2
sec x = 1/cos x Equation 3
csc x = 1/sin x Equation 4
cot x = 1/tan x Equation 5

What are the 6 trig identities?

The six trigonometric identities or the trigonometric functions are Sine, Cosine, Tangent, Secant, Cosecant and Cotangent. They are abbreviated as sin, cos, tan, sec, cosec and cot.

What are the 6 reciprocal identities?

The reciprocals of the six fundamental trigonometric functions (sine, cosine, tangent, secant, cosecant, cotangent) are called reciprocal identities. The reciprocal identities are important trigonometric identities that are used to solve various problems in trigonometry.
