The Calculus without beating about the bush

Continuing the previous book, in this new publication we will address the simple integrals and the most important applications. The main idea is to once again present the subject of calculus in a direct manner and with the necessary and sufficient tools to continue in the Engineering course. Again, our desire is to generate motivation so that the "first major obstacle" that the subject represents can be overcome. However, it is worth mentioning the stanza of the song: "...I can't help you, this path there's no other who can do it for you. I'd like to insist, but the path only exists when you pass ..." (Acima do Sol, Skank).
