TITLE: Reference request: Oldest calculus, real analysis books with exercises?
QUESTION [13 upvotes]: Per the title, what are some of the oldest calculus, real analysis books out there with exercises? Maybe there are some hidden gems from before the 20th century out there.
Edit. Unsolved exercises are fine. Same with solved.

REPLY [4 votes]: Maria Agnesi is perhaps best (only?) known for the "witch of Agnesi" today, but her calculus textbook has much more than that to recommend it.  I'm not sure if it contains "exercises" in your sense of the word, though.
