Range of principal value of cos−1 is [0 , 𝜋] Hence, the principal value is 𝟐𝝅/𝟑. Rough We know that cos 60° = 1/2 θ = 60° = 60° × 𝜋/180 = 𝜋/3 Since (−1)/2 is negative Principal value is 𝜋 – θ i.e. π −𝜋/3 = 2𝜋/3. Show More Since cos 90° = 0, we have cos 1° cos 2° cos 3° …cos 90°… cos 179° = 0 cos(267°) + cos(273°) = 0 cos(268°) + cos(272°) = 0 cos(269°) + cos(271°) = 0 So all those cosines in the sum cancel out.
Felet du gör är att du skriver om cos2x1 - cos(x) till cos2xsin2x, detta stämmer inte. Det är ingen kvadrat på cosinus i nämnaren. Om man rättar
sin2 x +cos2 x = 1 cos2 x = 1 則sin 2? 的值等於(Ａ) (Ｂ) (Ｃ) (Ｄ) 3 8 4 4 8 1 8 解析：(Ｂ)∵ tan ? ?

When this notation is used, inverse functions could be confused with multiplicative inverses. The notation with the "arc" prefix avoids such a confusion, though "arcsec" for arcsecant can be confused with "arcsecond". cos − 1 (x y − 1 − x 2 1 − y 2 ) = π − cos − 1 z x y − 1 − x 2 1 − y 2 = cos ( π − cos − 1 z ) x y − 1 − x 2 1 − y 2 = − cos ( cos − 1 z )
prove sec (x) - tan (x)sin (x) =cos (x) and cot^2 (x) (1-cos^2 (x)) = cos^2 (x) 3:01. Hire me to help you with your Homework and Tests.

The inverse cosine `y=cos^(-1)(x)` or `y=acos(x)` or `y=arccos(x)` is such a function that `cos(y)=x`.
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.
