[makeItJONAS]

so much respect for this guy, especially as a junior in high school, the videos on youtube help a ton

great lectures. but why did we move from ephsilon notation to limit of a fn notation, when we haven't even defined what is the limit of a fn? particularly h approaching from -ve and +ve etc.? what do they mean rigorously?

This is very very nice to have online. Much appreciated as a supplement to the course.
