List of Integrals of Rational Functions - Integrands of The Form xm (a + b Xn)p

Integrands of The Form xm (a + b Xn)p

  • The resulting integrands are of the same form as the original integrand, so these reduction formulas can be repeatedly applied to drive the exponents m and p toward 0.
  • These reduction formulas can be used for integrands having integer and/or fractional exponents.

\int x^m \left(a+b\,x^n\right)^p dx = \frac{x^{m+1} \left(a+b\,x^n\right)^p}{m+n\,p+1}\,+\, \frac{a\,n\,p}{m+n\,p+1}\int x^m \left(a+b\,x^n\right)^{p-1}dx

\int x^m \left(a+b\,x^n\right)^p dx = -\frac{x^{m+1} \left(a+b\,x^n\right)^{p+1}}{a\,n (p+1)}\,+\, \frac{m+n (p+1)+1}{a\,n (p+1)}\int x^m \left(a+b\,x^n\right)^{p+1}dx

\int x^m \left(a+b\,x^n\right)^p dx = \frac{x^{m+1} \left(a+b\,x^n\right)^p}{m+1}\,-\, \frac{b\,n\,p}{m+1}\int x^{m+n} \left(a+b\,x^n\right)^{p-1}dx

Famous quotes containing the word form:

    Cruelty has a Human Heart,
    And jealousy a Human Face;
    Terror the Human Form Divine,
    And secrecy the Human Dress.
    William Blake (1757–1827)
