Definite integration involving modulus function

Definite  Integration Involving Modulus Function There is no anti-derivative for a modulus function; however we know it’s definition Thus we can split up our integral  in two parts. One  part must be completely negative and the another  must be completely positive. This strategy is known as splitting .  To split correctly it is better to  draw the modulus graph so that we can get the correct equation to represent each portion of the modulus graph . Example 1.  Find the value of  . Sol.  For a periodic function with period ,  , where is any natural number. Here    whose  …
