Apply the Product Rule
Differentiate the first factor while keeping the second, then add the second derivative term.
Formula: (uv)′ = u′v + uv′
Check the function, variable and any domain or bounds before calculating. Differentiation and integration results depend on the expression and conditions supplied, so an algebraically valid result still needs to match the original problem.
Check the result by differentiating or integrating the displayed expression as appropriate and confirm the required domain or bounds.
