Generally, we can write the function as follow: Dx= ln( 1 x+ a (5) z (x+ a)ndx= (x+ a)n+1. Ln x a dx cx a a ³ 5.

The most common application of integration is to find the area under the curve on a graph of a function.
Integration using tables while computer algebra systems such as mathematica have reduced the need for integration tables, sometimes the tables give a nicer or more useful form of the answer than the one that the cas will yield. Table of basic integrals basic forms (1) z xndx= 1 n+ 1 xn+1; ∫ cos u d u = sin u + c ∫ cos u d u = sin u + c. (d/dx) (sinx + c)= cos x +0.
If r (x) in (4) is one of the functions in the first column in table 2.1, choose yp in the same line and determine its undetermined coefficients by substituting yp and its derivatives into (4).

Where “c” is the arbitrary constant or constant of integration. The curve c with equation y = f (x) passes through the point (5, 65). ³e dx e cxx 4. ∫ cos x dx = sin x + c.
To work out the integral of more complicated functions than just the known ones, we have some integration rules.
∫ csc 2 u d u = −cot u + c ∫. This page lists some of the most common antiderivatives. ∫ e u d u = e u + c ∫ e u d u = e u + c. 1 1 n x dx cn x n ³ reciprocal, exponential, log 2.
So, equation (1) can be written as.

Also, any real number “c” is considered as a constant function and the derivative of the constant function is zero.
