SUMMARY

The integral of the function (x-5)/(x²-2x+2) has been successfully transformed using the substitution x-1=t, leading to the integral ∫(t-4)/(t²+1)dt. This integral is further simplified into two parts: ∫t/(t²+1)dt and -4∫1/(t²+1)dt. The final result is 0.5ln|t²+1|-4arctg(t)+C, which can be verified by differentiation to return to the original integrand.

PREREQUISITES
  • Understanding of integral calculus
  • Familiarity with substitution methods in integration
  • Knowledge of logarithmic and arctangent functions
  • Ability to differentiate functions to verify results
NEXT STEPS
  • Study advanced integration techniques, including integration by parts
  • Learn about the properties of logarithmic and trigonometric functions
  • Explore the use of substitution in solving complex integrals
  • Practice verifying integrals through differentiation
USEFUL FOR

Students and professionals in mathematics, particularly those focused on calculus and integral techniques, as well as educators teaching integration methods.

[tex]\int[/tex](x-5)/(x2-2x+2)dx

(x-5)/(x2-2x+2)=(x-1-4)/((x-1)2+1)

x-1=t therefore x=t+1

dx=x'dt=(t+1)'dt=dt


[tex]\int[/tex](x-5)/(x2-2x+2)dx=[tex]\int[/tex](t-4)/(t2+1)dt

=[tex]\int[/tex]t/(t2+1)dt-4[tex]\int[/tex]1/(t2+1)dt

=0.5ln|t2+1|-4arctg(t)+c

If you differentiate your answer, you should be able to get back to your original integrand.
