WebbThe easiest way is to see that cos 2φ = cos²φ - sin²φ = 2 cos²φ - 1 or 1 - 2sin²φ by the cosine double angle formula and the Pythagorean identity. Now substitute 2φ = θ into … WebbStep 1: We can use the result in proof 1 to prove the second cofunction identity. If we substitute π/2 – v in the first formula, we obtain. Step 2: Evaluate the value trigonometric functions that are solvable. Step 3: Since the symbol v is arbitrary, the derived equation is equivalent to the second cofunction formula. poppy lottery advert
