Hey, I'm sorry, a little ambiguity here. You want to understand just the integration technique applied in this particular question?
Or the concept of using integration in continuous payments?
anyway, in this ex, they have considered (e^(−0.08))×0.8 as one entity, let say "a". So integrate "a^t", u get a^t/log a.
