Apply the product rule for differentiation: $(f\cdot g)'=f'\cdot g+f\cdot g'$, where $f=\ln\left(x\right)$ and $g=\cos\left(x\right)$

$\frac{d}{dx}\left(\ln\left(x\right)\right)\cos\left(x\right)+\ln\left(x\right)\frac{d}{dx}\left(\cos\left(x\right)\right)$
Learn how to solve limits by direct substitution problems step by step online. Find the derivative of ln(x)cos(x). Apply the product rule for differentiation: (f\cdot g)'=f'\cdot g+f\cdot g', where f=\ln\left(x\right) and g=\cos\left(x\right). The derivative of the cosine of a function is equal to minus the sine of the function times the derivative of the function, in other words, if f(x) = \cos(x), then f'(x) = -\sin(x)\cdot D_x(x). The derivative of the natural logarithm of a function is equal to the derivative of the function divided by that function. If f(x)=ln\:a (where a is a function of x), then \displaystyle f'(x)=\frac{a'}{a}. Multiply the fraction by the term .
