Do sin and csc go together
WebAll Pythagorean trig identities are mentioned below together. Each of them can be written in different forms by algebraic operations. i.e., each Pythagorean identity can be written in 3 forms as follows: sin 2 θ + cos 2 θ = 1 ⇒ 1 - sin 2 θ = cos 2 θ ⇒ 1 - cos 2 θ = sin 2 θ; sec 2 θ - tan 2 θ = 1 ⇒ sec 2 θ = 1 + tan 2 θ ⇒ sec 2 ... 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.
