Study Notes

Basic Integration Formulas

  • The integral of a constant multiplied by a function can be factored out: ∫kf(u)du = k∫f(u)du.
  • The integral of the sum or difference of two functions is the sum or difference of their integrals: ∫[f(u) ± g(u)] = ∫f(u)du ± ∫g(u)du.

Indefinite Integrals

  • The integral of ( du ) is ( u + C ).
  • For any integer ( n \neq -1 ), the integral of ( u^n ) is (\frac{u^{n+1}}{n+1} + C).

Exponential and Logarithmic Functions

  • The integral of (\frac{du}{u}) results in the natural logarithm: ( \ln|u| + C ).
  • The integral of ( e^u ) is simply ( e^u + C ).

Trigonometric Functions

  • The integral of ( \sin(u) ) yields: (-\cos(u) + C).
  • The integral of ( \cos(u) ) results in: ( \sin(u) + C ).
  • The integral of ( \tan(u) ) gives: (-\ln| \cos(u) | + C).
  • The integral of ( \cot(u) ) results in: ( \ln| \sin(u) | + C).
  • The integral of ( \sec(u) ) is expressed as: ( \ln| \sec(u) + \tan(u) | + C).
  • The integral of ( \csc(u) ) leads to: (- \ln| \csc(u) + \cot(u) | + C).
  • The integral of ( \sec^2(u) ) results in: ( \tan(u) + C).
  • The integral of ( \csc^2(u) ) yields: (- \cot(u) + C).
  • The integral of ( \sec(u) \tan(u) ) gives: ( \sec(u) + C).
  • The integral of ( \csc(u) \cot(u) ) results in: (- \csc(u) + C).

Inverse Trigonometric Functions

  • The integral of (\frac{du}{\sqrt{a^2 - u^2}}) produces ( \arcsin\left(\frac{u}{a}\right) + C ).
  • The integral of (\frac{du}{a^2 - u^2}) results in ( \frac{1}{a} \arctan\left(\frac{u}{a}\right) + C ).
  • The integral of ( \frac{du}{u\sqrt{u^2 - a^2}} ) yields ( \frac{1}{a} \text{arcsec}\left(\frac{|u|}{a}\right) + C ).
