WebApr 15, 2024 · prove the trigonometric equation with Pythagorean identities WebSecondly, the identity is tan²θ + 1 = sec²θ, not tan²θ - 1. Maybe this proof will be easier to follow: tan²θ + 1 = sin²θ/cos²θ + 1 = sin²θ/cos²θ + cos²θ/cos²θ = (sin²θ + cos²θ)/cos²θ //sin²θ + cos²θ = 1, which we substitute in. = 1/cos²θ = sec²θ Therefore, tan²θ + 1 = sec²θ.
