2 dni temu · Reciprocal Identities: These identities define the relationships between each trigonometric function and its reciprocal. cscθ = 1/sinθ. secθ = 1/cosθ. cotθ = 1/tanθ. Quotient Identities: These identities show that tangent and cotangent are ratios of sine and cosine. tanθ = sinθ/cosθ. cotθ = cosθ/sinθ.
