FAQs on Methods of Integration, Business Mathematics & Statistics Video Lecture - Business Mathematics and Statistics - B Com

1. What are the basic methods of integration?
Ans. The basic methods of integration include the power rule, substitution, integration by parts, partial fractions, and trigonometric substitution. These methods are used to find the antiderivative or integral of a function.
2. How does the power rule work in integration?
Ans. The power rule states that if the integral of x raised to the power of n is desired, the resulting integral will be (x^(n+1))/(n+1), where n is any real number except -1. This rule allows us to find the integral of functions that are powers of x.
3. What is substitution in integration and how does it work?
Ans. Substitution is a method used to simplify integrals by making a substitution of variables. It involves replacing the variable in the integral with a new variable that will simplify the integral. This is done by choosing an appropriate substitution that will transform the integral into a simpler form, which can then be easily evaluated.
4. How does integration by parts work?
Ans. Integration by parts is a method used to find the integral of a product of two functions. It is based on the product rule of differentiation. The formula for integration by parts is ∫(u dv) = uv - ∫(v du), where u and v are functions of x and du and dv represent their differentials. This method is useful when the integral of a product is difficult to evaluate directly.
5. What is the purpose of partial fractions in integration?
Ans. Partial fractions is a technique used to simplify the integration of rational functions. It involves decomposing a rational function into a sum of simpler fractions called partial fractions. This allows us to break down a complex integral into simpler integrals that can be evaluated more easily. Partial fractions are particularly useful when dealing with rational functions that contain polynomial factors.
