Indefinite Integral

  • Definition: The indefinite integral of a function f(x) is denoted by ∫f(x)dx.
  • It represents the family of antiderivatives of f(x).
  • The indefinite integral finds the area under the curve of a function.
  • The indefinite integral of a constant C is Cx + K, where K is the constant of integration.
  • The integral of the sum of two functions is the sum of their integrals.
  • The integral of a constant multiplied by a function is equal to the constant multiplied by the integral of the function.
  • The integral of the product of a constant and a function is equal to the constant multiplied by the integral of the function.
  • Basic integration formulas:
    • ∫1dx = x + C
    • ∫x^ndx = (x^(n+1))/(n+1) + C, (n ≠ -1)
    • ∫e^xdx = e^x + C
    • ∫a^xdx = (a^x)/(ln(a)) + C, (a > 0, a ≠ 1)
  • The integral of a power of the natural logarithm:
    • ∫ln(x)dx = xln(x) - x + C
  • The integral of a rational function:
    • ∫(1/x)dx = ln|x| + C
