Example Question #31 :Area Under A Curve
Find the area under the curve forfromto, rounded to the nearest integer.
Finding the area of a region is the same as integrating over the range of the function and it can be rewritten into the following:
Solution:
This function is negative from x=[-2,0], and positve everywhere else. Split this integral up into 2 pieces, multiplying x=[-2,0] region by -1, and sum everything up.
