$\frac{-1}{\sqrt{1-\left(2x\right)^2}}\frac{d}{dx}\left(2x\right)$
Learn how to solve calcul différentiel problems step by step online. d/dx(arccos(2x)). Apply the formula: \frac{d}{dx}\left(\arccos\left(\theta \right)\right)=\frac{-1}{\sqrt{1-\theta ^2}}\frac{d}{dx}\left(\theta \right), where x=2x. Apply the formula: \left(ab\right)^n=a^nb^n. Apply the formula: ab=ab, where ab=- 4x^2, a=-1 and b=4. Apply the formula: \frac{d}{dx}\left(nx\right)=n\frac{d}{dx}\left(x\right), where n=2.
