Thanks, image search is a good idea. Why did I not think of that. It was probably Silvanus' classic. I can't seem to find a picture of the cover from that age.

I think for us our first exposure was through the notion of instantaneous velocity in Physics. Our Physics classes were usually a step or two ahead and there the calculus was a little handwavy. The mathematics classes in the coming weeks would soon follow making the ideas a little more grounded.

It worked for us is all I can say. Were us is my group of high school friends.
