Fill in the blanks: 1. is a method depending on the product rule for differentiation, for articulating one integral in provisions of another. 2. If f(x) and g(x) be two given functions of x we know that |{f(x).8(x)} = dx 3. 4. 5. The integral of the product of two functions = first function x integration of second- Integral of The success of the integration by parts method depends upon choosing the first function in such a way that the second term on the right hand side may be easy to the product is regarded as the....... ......... function. If the integral on the right-hand side reverts to the form, the value of the integral can be immediately inferred by transposing the forms to the left-hand side.
