You may have to use algebra, educated guess-and-check, and/or recognize an integrand as the result of a product or quotient calculation. Note, when using FTOC part I, you do not need to check that the hypothesis is true before using the consequent; This is the only theorem where we will be allowed to do this 'omission of checking hypothesis'.
