It's equal to 2 (sinx)^2. Proof is from the double angle formula. Expand out cos 2x using the double angle formula as 2 cos^2 x - 1. We know cos = 1 / sec, so, this becomes: (2 / sec^2 x) - 1.

Free trigonometric identities - list trigonometric identities by request step-by-step 5.3 Half-Angle Formulas At times is it important to know the value of the trigonometric functions for half-angles. For example, using these formulas we can transform an expression with exponents to one without exponents, but whose angles are multiples of the original angle. Identities related to sin 2x, cos2x, tan 2x, sin3x, cos3x, and tan3x : Sin 2x = Sin 2x = sin(2x)=2sin(x). cos(x) Sin(2x) = 2 * sin(x)cos(x) Proof: To express Sine, the formula of “Angle Addition” can be used. 2018-05-30 · Sum to product identities are identities where we convert sin x + sin y or cos x + cos y into product of sin and cos. For example - sin x + sin y is 2 sin (x+y)/2 cos (x -y)/2, cos x - cos y is 3 Euler’s formula The central mathematical fact that we are interested in here is generally called \Euler’s formula", and written ei = cos + isin Using equations 2 the real and imaginary parts of this formula are cos = 1 2 (ei + e i ) sin = 1 2i (ei e i ) (which, if you are familiar with hyperbolic functions, explains the name of the Din formula cos2x = 1 – 2sin 2 x, deducem , x I R, iar din formula cos 2x = 2cos 2 x – 1, decucem , ( ) x I R. Aceste doua ultime formule se mai numesc formule de liniarizare si ele sunt utile in aplicatii intrucat permit trecerea de la patrate de functii trigonometrice la functii trigonometrice la puterea intai, insa avand argumentul dublu.
