1) (x^2+x) |(0;1) = (1^2+1)-(0^2+0)= 2
2) (2/3*x^(3/2)+2√x) |(0;1) = (2/3*1+2√1)-(2/3*0+2√0) = 2/3+2 = 8/3
3) (2tg x + cos x) |(0;Π/3) = (2√3+1/2) -(2*0+1) = 2√3 - 1/2
4) 1/3*ln|3x+1| | (0;1) = 1/3*ln 4 - 1/3*ln 1 = 1/3*ln 4
5) (x^2+ln |x|) |(1;2) = (2^2+ln 2)-(1^2+ln 1) = 4+ln 2-1 = 3+ln 2
6) 2√(16+x^2) |(0;3) = 2*(√(16+9)-√(16+0)) = 2*(5-4) = 2
