OBJECTIVE: I am looking for some resources/books to learn Calculus. I have searched archives here and noticed that recommended books from reputed authors Spivak, Courant, Hardy, Apostol are based on rigor. I do not want rigor, proofs, theorems and analysis. I want practical side of Calculus. Of course this does not mean I don't like theory, I do want to learn fundamentals of Calculus, I just don't want to be bogged down into too much of details (the way school taught me to hate Math)
BACKGROUND: My field of work is Data Science and Machine-Learning and I need a good grasp of Statistics and Probability, but every book I pick up on these subjects talks in weird inverted-italicised-9 and elongated-corneres-trimmed-S symbols (differential and integral symbols respectively). I have worked through colege algebra from edX MOOC with Arizona State University) and Pre-Calculus from http://www.coolmath.com/ and currently studying Calculus for the Ambitious.
Any recources ?
