Calculus trigonometric derivatives and integrals strategy for evaluating r sinm(x)cosn(x)dx (a) if the power n of cosine is odd (n =2k +1), save one cosine factor and use cos2(x)=1sin2(x)to express the rest of the factors in terms of sine:
They can be represented on a number line. By this rule the above integration of squared term is justified, i.e.∫x 2 dx. Indefinite integral :∫f x dx f x c( ) = +( ) There are two which are the most important and come up the most:

Integration rules and formulas integral of a function a function ϕ(x) is called a primitive or an antiderivative of a function f(x), if ?'(x) = f(x). Integral calculus formula sheet derivative rules: For the following, let u and v be functions of x, let n be an integer, and let a, c, and c be constants.
