નિયત સંકલન

નીચે આપેલાં નિયત સંકલિતને સરવાળાના લક્ષ સ્વરૂપે મેળવો :
$integral from 0 to 2 of space open parentheses straight x space plus space 3 close parentheses space dx$

અહી, વિધેય f(x) = x + 3 એ [0, 2]માં સતત છે.

[0, 2]નું સમાન લંબાઈના n ઉપાંતરાલોમાં વિભાજન કરતાં,

પ્રત્યેક ઉપાંતરાલની લંબાઈ $straight h space equals space fraction numerator straight b space minus space straight a over denominator straight n end fraction space equals space fraction numerator 2 space minus space 0 over denominator straight n end fraction space equals space 2 over straight n.$

અહીં, a = 0, b = 2 અને

$straight f open parentheses straight a space plus space ih close parentheses space equals space straight f open parentheses 0 space plus space ih close parentheses space equals space straight f open parentheses ih close parentheses space equals space ih space plus space 3$

હવે, વ્યાખ્યા પ્રમાણે,

$integral from 0 to 2 of space open parentheses straight x space plus space 3 close parentheses space dx space equals space limit as straight n rightwards arrow infinity of space straight h space sum from straight i space equals space 1 to straight n of space straight f space open parentheses straight a space plus space ih close parentheses$

$equals space limit as straight n rightwards arrow infinity of space 2 over straight h space sum from straight i space equals space 1 to straight n of space open parentheses ih space plus space 3 close parentheses equals space limit as straight n rightwards arrow infinity of space 2 over straight h space open square brackets straight h space sum from straight i space equals space 1 to straight n of space straight i space plus space 3 space sum from straight i space equals space 1 to straight n of space 1 close square brackets equals space limit as straight n rightwards arrow infinity of space 2 over straight n space open square brackets 2 over straight n space times space straight n over 2 space open parentheses straight n space plus space 1 close parentheses space plus space 3 straight n close square brackets equals space limit as straight n rightwards arrow infinity of space open square brackets 2 space open parentheses 1 space plus space 1 over straight n close parentheses space plus space 6 close square brackets equals space 2 space open parentheses 1 space plus space 0 close parentheses space plus space 6 bold equals bold space bold 8$

નીચે આપેલાં નિયત સંકલિતને સરવાળાના લક્ષ સ્વરૂપે મેળવો :
$integral from log subscript straight e space 2 to log subscript straight e space 5 of space straight e to the power of straight x space dx$

નીચે આપેલાં નિયત સંકલિતને સરવાળાના લક્ષ સ્વરૂપે મેળવો :
$integral from 1 to 2 of space 3 to the power of straight x space dx$

નીચે આપેલાં નિયત સંકલિતને સરવાળાના લક્ષ સ્વરૂપે મેળવો :
$integral from negative 1 to 1 of space straight e to the power of straight x space dx$

નીચે આપેલાં નિયત સંકલિતને સરવાળાના લક્ષ સ્વરૂપે મેળવો :
$integral from 0 to 1 of space straight e to the power of 2 minus 3 straight x end exponent space dx$

નીચે આપેલાં નિયત સંકલિતને સરવાળાના લક્ષ સ્વરૂપે મેળવો :

$integral from 1 to 3 of space open parentheses straight x squared space plus space straight x close parentheses space dx$
