How do you use the half-angle identities to find all solutions on the interval [0,2pi) for the equation \displaystyle{{\sin}^{{2}}{x}}={{\cos}^{{2}}{\left(\frac{{x}}{{2}}\right)}} ? Explanation: Step 1: Add 1 to both sides: \displaystyle{2}{{\cos}^{{2}}{\left({2}{x}\right)}}={1} Step 2: Divide both sides Isolate the angle 2x, by following the reverse "order of operations". Explanation: Step 1: Add 1 to both sides: 2 cos 2 ( 2 x ) = 1 Step 2: Divide both sides cos2x skulle jag hellre skriva som cos(2x), alltså Cosinus för dubbla vinkeln.

Hence, the first cos 2X formula follows, as. cos ⁡ 2 X = cos ⁡ 2 X – sin ⁡ 2 X. \cos 2X = \cos ^ {2}X – \sin ^ {2}X cos2X = cos2 X – sin2 X. And for this reason, we know this formula as double the angle formula, because we are doubling the angle. Quick summary with stories.

\cos x = \sin 2x. Då har vi en sammansatt funktion och derivatan blir D\sin 2x = \cos 2x \cdot 2 = 2\cos 2x. \frac{\cos^2x +\sin^2 x}{\cos^2x} = \frac{1}{\cos^2x}.
