what is the integral of dx So you would write it like f x x The sign is a sigma and stands for sum In an integral you take the limit as x goes to zero So we replace the sigma with another type of s And the gets changed to a d So it is now written f x dx and it is the integral of f x with respect to x

Integration Rules Here are the most useful rules with examples below Examples Example what is the integral of sin x From the table above it is listed as being cos x C It is written as sin x dx cos x C Example what is the integral of 1 x From the table above it is listed as being ln x C It is written as The basic idea of Integral calculus is finding the area under a curve To find it exactly we can divide the area into infinite rectangles of infinitely small width and sum their areas calculus is great for working with infinite things
Dx dx is part of the integrand it identifies the variable used in integration g x C g x C is called the general anti derivative of f x f x C C is called the constant of integration it is an arbitrary constant If C C has a specific value from given conditions g x C g x C is called a particular antiderivative In fact there exist infinite integrals of this function because the derivative of any real constant C is zero and we can write as cos x dx sin x C It is the rule of integration to add an arbitrary constant C from the set of real numbers
