Trigonometric identities and equations pdf
WebThe Pythagorean trigonometric identities in trigonometry are derived from the Pythagoras theorem.The following are the 3 Pythagorean trig identities. sin 2 θ + cos 2 θ = 1. This can also be written as 1 - sin 2 θ = cos 2 θ ⇒ 1 - cos 2 θ = sin 2 θ; sec 2 θ - tan 2 θ = 1. This can also be written as sec 2 θ = 1 + tan 2 θ ⇒ sec 2 θ - 1 = tan 2 θ; csc 2 θ - cot 2 θ = 1. WebSolve each of the following equations, for 00 < x < 3600. 131 131 (i) sin (ii) sinx = 0.8 3 cosx sm x — cos2x tan2x— (i) Show that 1 — sin x (ii) Hence solve the equation 1. tan x, [2] [6] …

WebWhen proving this identity in the first step, rather than changing the cotangent to cos2x sin2x, we could have also substituted the identity cot2x = csc2x − 1. sinx 1 − cosx = 1 + cosx sinx. Multiply the left-hand side of the equation by 1 + cosx 1 + cosx. sinx 1 − cosx = 1 + cosx sinx 1 + cosx 1 + cosx ⋅ sinx 1 − cosx = sin(1 + cosx ...
