Určte prvú deriváciu funkcie \(f\colon y = \frac{1}
{\cos x+3x^{2}} \).
\(f^{\prime}(x) = \frac{\sin x-6x}
{(3x^{2}+\cos x)^{2}} ;\ x\in \mathbb{R}\)
\(f^{\prime}(x) = \frac{6x-\sin x}
{(3x^{2}+\cos x)^{2}} ;\ x\in \mathbb{R}\)
\(f^{\prime}(x) = \frac{\sin x-6x}
{3x^{2}+\cos x};\ x\in \mathbb{R}\)
\(f^{\prime}(x) = \frac{6x-\sin x}
{3x^{2}+\cos x};\ x\in \mathbb{R}\)
