Определённый интегргал

tex] intlimits^ frac{15}{10} _0 ( frac{x^2+2x+1}{x+1} ) , dx [/tex]
$intlimits^4_1 (1+5x+ frac{3 sqrt{x} }{2} ) , dx$

Answer 1

$= intlimits^4_1 {} , dx + intlimits^4_1 {5x} , dx + intlimits^4_1 {3x^1/2/2} , dx =x |4-x |1+5x^2/2 |4 -5x^2/2 |1+ x^3/2 |4 -x^3/2 |1=4-1+40 -2,5+8-1=47,5$
