anonymous 4 years ago Integral over adjacent intervals interval from 2 to 9 f(x) dx= 3.8 and interval from 6 to 9 f(x)dx=13 find interval from 2 to 6 f(x)dx ??

1. TuringTest

$\int_{2}^{9}f(x)dx=\int_{2}^{6}f(x)dx+\int_{6}^{9}f(x)dx$therefor$\int_{2}^{6}f(x)dx=\int_{2}^{9}f(x)dx-\int_{6}^{9}f(x)dx$
