hi
if we are asked to work out the integral of a curve say from -1 to 1, and in the domain [-1,0] the curve lies below the x axis, (that is, it has negative y values), then the integral in the domain [-1,1] is calculated as normal (single integral calculation from -1 to 1) or do we have to make the integral in [-1,0] negative.
its asking for the "integral from -1 to 1" it's not asking for the area. so i dont have to change the sign for the integral on [-1,0] right?
