Genom omskrivning med formeln för dubbla vinkeln blir ekvationen. 2sinx Jag får det till: PF(sinx^2)=PF((1-cos(2x))/2)=x/2-sin(2x)/4+C Det liknar sinus för dubbla vinkeln som blir 1-cos2x. Hälsningar. Hans L visa att tan x = sin2x/ 1 + cos2x bägge är dubbla vinkeln inte upphöjt. sin(2x) = 2sin(x)cos(x) och 1+cos(2x) = 2(cos(x))^2.

Double-Angle Identities. sin(2x) = 2 sin(x) cos(x). cos(2x) = cos2(x) – sin2(x) = 1 – 2 sin2(x) = 2 cos2(x) – 1. tan ( 2 x ) = 2 tan ( x ) 1 − tan 2 ( x ) \tan(2x) Sin 2X = 2 Sin X Cos X. Cos 2X = Cos2X - Sin2X.

The word ‘trigonometry’ being driven from the Greek words’ ‘trigon’ and ‘metron’ and it means ‘measuring the sides of a triangle’. In this Chapter, we will generalize the concept and Cos 2X formula of one such trigonometric ratios namely cos 2X with other trigonometric ratios.

cos2X =Cos2X -sin2X. Cos2X =(1-sin2 X ) -sin2 X (Since ,cos2X=(1-sin2 X ) cos2X=1-sin2 X -sin2 X. So. Cos2X=1-(sin2 X+sin2 X) Hence cos2x =1-2sin2 X. Cos2x =2COS2X-1. To derive this we need to start from the eariler derivation As we already know that. cos2X =Cos2X -sin2X. Cos2x=cos2X-(1-cos2X){Since sin2x=(1-cos2X)} Cos2x =cos2X-1 +cos2X. cos2X=(cos2X+cos2X)-1
