Find {eq}f'(x), {/eq} if {eq}f(x) = x^3 \cot x. {/eq}
Question:
Find {eq}f'(x), {/eq} if {eq}f(x) = x^3 \cot x. {/eq}
Product rule of differentiation:
Assume that {eq}u {/eq} and {eq}v {/eq} be two differentiable functions, then their product {eq}(uv) {/eq} is also differentiable,
The derivative of that product {eq}uv {/eq} is {eq}u'v + v'u {/eq}.
And also know that the derivative of {eq}x^n {/eq} is {eq}nx^{n - 1} {/eq}, where {eq}n {/eq} is a real number.
