WebIn the given range 0 < θ < 90 ∘, tan θ > 0 and sin θ > 0. From [ i], we see that the right-hand side, being the product of two squared values is necessarily positive. So. (1) tan 2 θ − sin 2 θ > 0 tan 2 θ > sin 2 θ. And as tan θ and sin θ are both positive in our range, ( 1) implies that. tan θ > sin θ for 0 < θ < 90 ∘. WebFind the value of tan 120°. Solution: tan 120° = tan (180 - 60)° = - tan 60°; since we know, tan (180° - θ) = - tan θ = - √3 Trigonometric Functions Basic Trigonometric Ratios and Their Names Restrictions of Trigonometrical Ratios Reciprocal Relations of Trigonometric Ratios Quotient Relations of Trigonometric Ratios Limit of Trigonometric Ratios
Web7 years ago. The 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 those last two equations and solve for sin θ/2 and cos θ/2.
