 · Simplify tan^2 x sec^2 Ans 1 Use trig identity 1 tan^2 x = sec^2 x tan^2 x sec^2 x = 1Using the fundemental identities and the Pythagorean Identities, I go over multiple examples of verifying trigonometric identities It is very important in pLHS = 1 sin ⁡ θ cos ⁡ θ = ( 1 sin ⁡ θ) cos ⁡ θ) × ( 1 − sin ⁡ θ) 1 − sin ⁡ θ = 1 − sin 2 ⁡ θ cos ⁡ θ ( 1 − sin ⁡ θ) = cos 2 ⁡ θ cos ⁡ θ ( 1 − sin ⁡ θ) = cos ⁡ θ ( 1 − sin ⁡ θ) = RHS Restrictions undefined where cos ⁡ θ = 0, sin ⁡ θ = 1 and where tan ⁡ θ is undefined Therefore θ ≠ 90 °;

Sums or difference of Sines or Cosines · tan²θ = sin²θ cos²θ = 1 That is wrong tan²θ = sin²θ/cos²θ Secondly, the identity is tan²θ 1 = sec²θ, not tan²θ 1 Maybe this proof will be easier to followGraphs of Inverse Trigonometric Functions;
