There is no point to using partial fractions in this problem. I would split this into two integrals like so:Geocentric said:Homework Statement
I am stuck on this integral.
1) (a - bx)/(a^2 + b^2 - 2abx)^(3/2)
I tried some substitutions but end up with complicated expressions. How to decompose into partial fractions when the denominator is raised to fractional powers? Can anyone please help me out?
Integration by partial fractions is a method used in calculus to simplify complex fractions into smaller, more manageable fractions. This method is used to solve integrals, which are expressions that involve the process of finding the area under a curve.
Integration by partial fractions is used when we have a rational function, which is a fraction with polynomials in the numerator and denominator. By using this method, we can break down the rational function into smaller fractions that are easier to integrate.
The first step in integration by partial fractions is to factor the denominator of the rational function into linear or irreducible quadratic factors. Then, we use the partial fraction decomposition technique to express the rational function as a sum of simpler fractions with unknown coefficients. These coefficients can be solved for by equating the coefficients of the corresponding powers of x on both sides of the equation.
There are two types of partial fractions: proper and improper. Proper partial fractions have a smaller degree in the numerator than in the denominator, while improper partial fractions have a larger degree in the numerator than in the denominator. The approach to solving these types of partial fractions may differ slightly, but the overall method remains the same.
No, integration by partial fractions can only be used for rational functions. If the integral involves other types of functions, such as trigonometric or exponential functions, other methods must be used to solve the integral.
