`int_(0)^(1)|5x-3|dx` का मान ज्ञात कीजिए। |
|
Answer» `|5x-3|={{:(5x-3",",xle3//5),(-(5x-3)",",xlt3//5):}` `therefore" "int_(0)^(1)|5x-3|dx=int_(0)^(3//5)|5x-3|dx+int_(3//5)^(1)|5x-3|dx` `=int_(0)^(3//5)-(5x-3)dx+int_(3//5)^(1)(5x-3)dx` `=-[(5x^(2))/(2)-3x]_(0)^(3//5)+[(5x^(2))/(2)-3x]_(3//5)^(1)` `=-[(5)/(2)xx(9)/(25)-3xx(3)/(5)-0]+[((5)/(2)-3)-((5)/(2)xx(9)/(25)-3xx(3)/(5))]` `=-(9)/(10)+(9)/(5)-(1)/(2)-(9)/(10)+(9)/(5)` `=-(18)/(10)+(18)/(5)-(1)/(2)=(-18+36-5)/(10)` `=(13)/(10)` |
