Definite integral gives you the area, and area can't be negative. But while doing exercises, i cam across a lot of definite integrals, which after integrating, were giving negative answers. Why is it so?

    Area in a direction can be negative; maybe

    its either that or youve got your numbers backwards and are subtracting the smaller from the larger

    15 - 3 = 12 3 - 15 = -12

    For example, when you integrate this definite integral, \[\int\limits_{-1}^{-3} (x-1)^{-3} dx\] the answer is -3/32 is it so because of the negative limits?

    you can flip your bounds and it makes a (-) in front

    it simply means that the area that you want is to the left of x=0

    since you are working in a region that is "negative" to begin with, it gonne be a "negative" area
