Explanation Given Information: The function is g ( x ) = ( cos x ) ( cot x ) . Formula Used: The product rule is used which can be represented as follows: d d x ( x ⋅ y ) = d d x ( x ) ⋅ y + x ⋅ d y d x The quotient rule is used which can be represented as follows: d d x ( x y ) = d d x ( x ) ⋅ y − x ⋅ d y d x y 2 The following derivative formulas are used: d d x ( sin x ) = cos x d d x ( cos x ) = − sin x Calculation: Consider the function g ( x ) = ( cos x ) ( cot x ) . Represent the function in the form of d y d x . d d x ( cos x ) ( cot x ) Then apply the product rule to the function d d x ( cos x ) ( cot x ) = ( cot x ) ⋅ d d x ( cos x ) + ( cos x ) d d x ( cot x ) Further solve as, g ′ ( x ) = ( cot x ) ⋅ ( − sin x ) + ( cos x ) d d x ( cos x sin x ) Then apply the quotient rule to the function g ′ ( x ) = ( cot x ) ⋅ ( − sin x ) + ( cos x ) d d x ( cos x sin x ) = ( cot x ) ⋅ ( − sin x ) + ( cos x ) ( sin x ) ⋅ d d x ( cos x ) − ( cos x ) ⋅ d d x ( s
