Hello HMcCoy,

I was curious about a property relating to calculus. Why does subtracting the upper bound by the lower bound of a definite integral give you it's area? It's just strange to me considering the different types of graphs you can have like a negative parabola and a positive parabola.

Example: $$\int_a^bf(x)dx = F(b) - F(a) = Area$$

Also, can you revert TibetPrime's action on my personal user rights:

"23:36, August 28, 2015 TibetPrime (wall | contribs) changed group membership for User:Anthony Jacquez from rollback, moderator and poweruser to poweruser"

He never gave a reason for the action, so I don't believe the action can be valid.

Thanks,

Anthony Jacquez
