Differentiation Under Integral Sign and Error Function

Differentiation under Integral Sign, DUIS  Introduction Not all integrals can be evaluated using analytical techniques, such as integration by substitution, by parts or by partial fractions. People come up with different ways of solving the integrals and DUIS is one of them. The class of definite integrals can be treated as integrals of function of… Continue reading Differentiation Under Integral Sign and Error Function

Differential Equations II

Prerequisite : Differential Equations I Introduction In the previous post on differential equations, we looked at various differential equations of 1st order and 1st degree; but we had no clue about their nature, behavior and the fields of their application. Since derivatives are a tool to measure the rate of change of one quantity w.r.t.… Continue reading Differential Equations II
