02a f x dx. Since integration is almost the inverse operation of differentiation recollection of formulas and processes for differentiation already tells the most important formulas for integration. To represent the antiderivative of f the integral symbol symbol is introduced.
Ab f x dx ac f x dx cb f x dx P 3.
Int xgamma dx fracxgamma 1r 1 C. X n d x 1 n 1 x n 1 C unless n 1 e x d x e x C 1 x d x ln. Only one of these gives a result for du that we can use to integrate the given expression and thats the first one. Applications of each formula can be found on the following pages.
