Calculus "One of the greatest contributions to modern mathematics, science, and engineering was the invention of calculus toward the end of the 17th century," states the New Book of Popular Science. Without the invention of calculus, many technological achievements, such as the moon landing, would have been difficult. The word “calculus” comes from the Latin word meaning pebble. This is probably because many years ago people used pebbles to count and solve arithmetic problems. The two people who contributed immensely to the discovery of the theorems of calculus were Sir Isaac Newton of England and Baron Gottfried Wilhelm of Germany. They discovered these theorems in the 17th century, a few years apart. Isaac Newton was considered one of the greatest physicists of all time. He applied calculus to his theories of motion and gravitational attraction. He was able to discover a function and mathematically describe the movement of all objects in the universe. Calculus was invented to help solve problems related to “changing or variable” quantities. Calculation is considered a “mathematics of change”. There are some basic or general parts of the calculation. Some of them are functions, derivatives, primitives, sequences, integral functions and multivariate calculations. Some think calculus is too difficult or impossible to learn without a lot of memorization, but if you think calculus is all about memorizing, you won't get the learning object....
