To find the derivative of the function \( f(x) = x \cos x \), we will use the product rule of differentiation. The product rule states that if you have two functions \( u \) and \( v \), then the derivative of their product is given by: \[ f'(x) = u'v + uv' \] where \( u' \) is the derivative of \( u \) and \( v' \) is the derivative of \( v \). ...
