... Concept of Mathematics Concept Introduction: Integration by substitution is also d as u-substitution in calculus. It is one of the various different techniques of finding the integrals. (Anton, Bivens, & Davis, 2012, p. 281-282) By using the key theorem of calculus frequently involves in finding an anti-derivative. For reasons like this one and others, u-substitution or integration by substitution is an important instrument for mathematicians. Integration by substitution works as the counterpart to the chain rule of differentiation. (Challis & Gretton, 2010, p. 126-127)
Integration is mostly defined as the inverse process of differentiation. Integration, in calculus, method of determinin...
