Thanks

That sounds about right. Geometric series are C2 aren't they?
Differentiation's not required either. . . If it's not on your spec, you don't need to know it, but it's nice to know

6. tbh C1 is nothing Sn formula, proof x= -b +- b^ [quadratic formula]

C2 geometric series

Tomorrow C1 will be Average Paper
C2 is gonna be a Killlllllllllllllller
