Calculus Mission

When Calculus was first invented, there were three students who were determined to pass their knowledge of the subject onto their high school peers. How were they going to do this, though? The main question was how they were going to be able to teach their peers something they had so much trouble doing themselves. One of the three students had a brilliant idea – MAKE A TEXT BOOK! They knew they would have to work together in order to get the Text Book finished, and they were sure that they would be unable to complete the entire Text Book without your help. Do you think you can help them?
