Calculus... one of the greatest inventions of mathematics. It is the study of change and is a fundamental concept that has been 'integrated' into the natural world. :P From projectile motion, to economy, to population growth, calculus has applications in many areas. 'Introduction to Differential Calculus' will provide a definitive course that is designed to help students understand the mathematical function and its derivatives in further detail.

Calculus surrounds all of us every day. But most people either don't want to learn about this glorious subject, or find it too difficult. That is where this book comes in. It will explain what calculus is, and include detailed examples to help you understand. It is understandable if you hear the word calculus, and instantly run away screaming, but if you choose to stick around, you might find your way into a fun world that will keep you entertained and enlightened.

It looks like a math textbook, doesn't it? Well, it's not. This is something far less sinister. This is a story of a murder. ~*~ Calculus II is the son of Abacus and her husband Calculus I, two Roman plebeians who serve Emperor Mathematicus. Unfortunately, life as a common plebeian is not all it's cracked up to be. For starters, plebeians aren't allowed to attend school, so Cal has to come up with his own methods of staving off boredom. Luckily, he and his friends stumble across a crime scene, and decide that solving the problem of the mystery murderer is just the thing they need to exercise their brain cells. As their calculations finally start to add up, only one question remains: will they come to the right answer? Disclaimer I: This book does not really teach anything math-related. In fact, this book does not really teach much of anything-related. Disclaimer II: This book may contain the occasional Harry Potter reference.
