Trigonometric identities worksheet for verifying equations.
Worksheet titled "G11A 4.2 Verifying Trigonometric Identities" with four trigonometric equations to verify, including cot²θ csc²θ - cot²θ = cot⁴θ, tanθ csc²θ - tanθ = cotθ, (1 + cscθ)/secθ = cosθ + cotθ, and (tanx - secx)/(tanx + secx) = (tan²x - 1)/sec²x.
