Linear Integral Equations. A general type of integral equation, $ g (x) y (x) = f (x) + \lambda \int_a^\Box K (x, t) y (t) dt$ is called linear integral equation as only linear operations are performed in the equation. The one, which is not linear, is obviously called a "Non-linear integral equation". We generally mean linear integral equation ... One involves working out the general form for an integral, then differentiating this form and solving equations to match undetermined symbolic parameters. Even for quite simple integrands, the equations generated in this way can be highly complex and require Mathematica's strong algebraic computation capabilities to solve.

Here are the steps we followed: Choose u u and v′ v ′ (one to differentiate and the other to integrate) Differentiate u u to give u′ u ′.Since there are no path singularities and the behavior is monotonic, you you in effect reverse the integral test on infinite series. That is, find values of a for which the corresponding infinite sum will converge. This is done with SumConvergence. SumConvergence[(x^(a - 1))/(1 + x), x]
