Tangent squared identity
WebThe subtraction of the tan squared of angle from secant squared of angle is equal to one and it is called as the Pythagorean identity of secant and tangent functions. sec 2 θ − tan 2 θ = 1 Popular forms The Pythagorean identity of secant and tan functions can also be written popularly in two other forms. sec 2 x − tan 2 x = 1 sec 2 A − tan 2 A = 1 http://www.math.com/tables/trig/identities.htm
Tangent squared identity
Did you know?
WebYou would need an expression to work with. For example: Given sinα = 3 5 and cosα = − 4 5, you could find sin2α by using the double angle identity. sin2α = 2sinαcosα. sin2α = 2(3 5)( − 4 5) = − 24 25. You could find cos2α by using any of: cos2α = cos2α −sin2α. cos2α = 1 −2sin2α. cos2α = 2cos2α − 1. WebThe 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. Then the tangent identity just follow …
WebApr 14, 2024 · Using the identity \sin2\theta=2\sin\theta\cos\theta sin2θ = 2sinθcosθ gives X = ( sinθsin2θ)2 = ( sinθ2sinθcosθ)2 = 4cos2 θ. Therefore, the answer is (b).
