Nettet3. mar. 2024 · Here is the answer:- Explanation: 1 + tan2θ = sec2θ tanθ = sinθ cosθ and secθ = 1 cosθ 1 + sin2θ cos2θ = 1 cos2θ cos2θ +sin2θ/sin2θ = 1 cos2θ further on solving you would get both sides equal to sec^2 theta so it is proved. Answer link Nettet汉林学院 – Mr. Zhao Chapter 5 Trigonometric Ratios. Review Trigonometry is the branch of mathematics that deals with the properties of triangles and calculations based on these properties. The ratios of the sides of a right triangle are called trigonometric ratios. Three common trigonometric ratios are the sine (sin), cosine (cos), and tangent (tan).
