Texts: Consider the area between the graphs +2y=0 and z+8=0. This area can be computed in two different ways using integrals.
First of all, it can be computed as a sum of two integrals:
∫(a to b) (2y) dy + ∫(a to b) (z+8) dz
Alternatively, this area can be computed as a single integral:
∫(a to b) (2y + z+8) dz
Where a and b are the limits of integration.
Either way, we find that the area is given by the equation:
