 There once was a man named Newton who wanted to know how things worked. He developed a system called calculus but neglected to publish his work. In a different part of Europe, Leibniz got to it first. Both helped in developing mathematics and here is the end of the verse. For certain continuous functions, the limits of slopes can be found. This concept is called the derivative with many nice rules each renowned. The power rule for polynomials, the product rule for multiplying. The chain rule is for compositions, the quotient rules for dividing. To integrate various functions, some techniques you will have to know. The power rule for polynomials, rational functions you can decompose. By parts can be useful for products and use of for some compositions. Coordinate conversions are similar, you could say the two are synonyms. O Calculus is very useful, it calculates things all around. We can use it to understand physics and things so all the unknowns can be found. O Calculus is very useful, it calculates things all around.
