Integrating a Tricky Fraction: Solving ∫(1/(x^2-x+1)dx

In summary, integration of a fraction is the process of finding the antiderivative of a fraction, which is the reverse of differentiation. It is important in solving various mathematical problems and is a fundamental concept in calculus. The general formula for integrating a fraction is ∫(f(x)/g(x))dx = ln|g(x)| + C, and there are different methods for integration such as substitution, integration by parts, partial fraction decomposition, and trigonometric substitution. To improve skills in integrating fractions, practice and understanding of concepts are key, and additional help can be sought from textbooks, online resources, or a math tutor.

Homework Statement



∫(1/(x^2-x+1)dx

Homework Equations



No idea


The Attempt at a Solution



I tried this by the subsitution method but that attempt was feeble as it only complicated the integral even further.
let t=x^2-x+1

this integral can neither be split into partial fractions.

I have no idea how to proceed forward.

Write (x^2 - x +1) as (x-1/2)^2 +3/4. Then make the substitution u=x-1/2. Now the integrand is in the form of 1/(u^2 + a^2), which hopefully you know how to do with a trigonometric substitution.
 

1. What is integration of a fraction?

Integration of a fraction is a mathematical process that involves finding the antiderivative of a fraction. It is the reverse process of differentiation, and it helps in determining the original function from its derivative.

2. Why is integration of a fraction important?

Integration of a fraction is important because it helps in solving a wide range of mathematical problems, including area under a curve, volume of irregular shapes, and many other real-world applications. It is also a fundamental concept in calculus and is used in many other branches of mathematics and science.

3. What is the general formula for integrating a fraction?

The general formula for integrating a fraction is ∫(f(x)/g(x))dx = ln|g(x)| + C, where f(x) and g(x) are functions and C is the constant of integration. This formula is known as the quotient rule of integration.

4. What are the different methods for integrating a fraction?

There are several methods for integrating a fraction, including the substitution method, integration by parts, partial fraction decomposition, and trigonometric substitution. Each method is useful for different types of fractions and functions, and it is important to choose the appropriate method for the given problem.

5. How can I improve my skills in integrating fractions?

The best way to improve your skills in integrating fractions is through practice. Solve as many problems as you can, and also try to understand the concepts behind each method of integration. You can also seek help from textbooks, online resources, or consult a math tutor for additional guidance.
