Learn how to derive and use the cos2x formula in trigonometry to find the value of the cosine function for double angles. Explore the different forms of cos2x in terms of sine, cosine, and tangent functions and their applications.
$\cos^2 x$ or $\cos^2 (x)$ can also mean $\cos(\cos(x))$. If you want to use this notation, you should note it, because it is less common. However, $\cos^{-1} x$ is often used instead of $\arccos (x)$, so often does not mean the same as $(\cos x)^{-1} = \frac{1}{\cos x} = \sec x$.
Funkcja cosinus. Funkcja cosinus jest określona w trójkącie prostokątnym jako stosunek przyprostokątnej przyległej i przeciwprostokątnej. Funkcja jest definiowana od −∞ do +∞ i przyjmuje wartości od −1 do 1. A B C a b c α β. cos α = b c cos β = a c.
