Q. Find the derivative of f(x) f(x) .\newlinef(x)=xsin(x)f(x)= \begin{array}{l} f(x)=x \sin (x) \\ f^{\prime}(x)= \end{array}
  1. Apply Product Rule: Apply the product rule for differentiation.\newlineThe product rule states that the derivative of a product of two functions is the derivative of the first function times the second function plus the first function times the derivative of the second function.\newlineSo, for f(x)=xsin(x)f(x) = x \sin(x), we have:\newlinef(x)=ddx(x)sin(x)+xddx(sin(x))f'(x) = \frac{d}{dx}(x) \cdot \sin(x) + x \cdot \frac{d}{dx}(\sin(x))
  2. Differentiate Each Part: Differentiate each part.\newlineThe derivative of xx with respect to xx is 11, and the derivative of sin(x)\sin(x) with respect to xx is cos(x)\cos(x).\newlineSo we have:\newlinef(x)=1sin(x)+xcos(x)f'(x) = 1 \cdot \sin(x) + x \cdot \cos(x)
  3. Simplify Expression: Simplify the expression. f(x)=sin(x)+xcos(x)f'(x) = \sin(x) + x \cos(x) This is the simplified form of the derivative of f(x)=xsin(x)f(x) = x \sin(x).
