my assignment is to design a wine decanter using inegration methods. is it possible to have 2 very complex functions which r integrated and add them together to make a new function??

the two functions which i have are. they have been integrated

e^{-0.64x }(-156.25x^{2}-487.5x-762.5)

and

72.0716x-16.92cos(x)-0.5sin(x)cos(x)

if possible how would i do it??
