I am always happy when someone correct me with respect.

Reblog if you are 100% okay with a transgender person correcting you if you accidentally misgender them or use their dead name.

If each dead person became a ghost, there’d be more than 100-billion of them haunting us all. Creepy, but cool.

if you integrate y*dx for a rectangle x by y then you get the area is xy

I mean, true, but the derivation of an integral uses the formula of a rectangle, making this circular.

Basically the idea of integrals is that you add up the areas of infinitely many, infinitely skinny rectangles to find the area under the function, so you can’t use an integral to find the formula for the area of a rectangle.
