Derivative of cosine, $g(x)=\cos x$ is: \[\forall x \in \mathbb{R}, \quad g'(x) = - \sin x\] So, we have: \[\begin{aligned} f^{\prime}(x)&=\frac{1}{\cos^{\prime}(f(x))}\\ &=-\frac{1}{\sin (f(x))}\\ &=-\frac{1}{\sin (\arccos x)}\\ \end{alig...
1/x = x-1 d/dx 1/x = -1/x2 Furthermore, it also holds when c is fractional. This allows us to calculate the derivative of, for example, the square root: d/dx sqrt(x) = d/dx x1/2= 1/2 x-1/2= 1/2sqrt(x) Exponentials and Logarithms ...
