There are many applications in which calculus is used in real life, such as calculating minimum payments due on credit cards, determining the length of cable required to connect two substations and evaluating survey data. Just as geometry is the mathematical study of shapes, calculus is the mathematical study of change.
Know MoreOne of the most common ways in which calculus is used in everyday life is the calculation of monthly payments by credit card companies. When the customer's statement is processed, it is important that the minimum amount due reflects all the current variables. Calculus comes into play because the companies consider fluctuating interest rates and changing balances.
The length of cables used to connect substations has to be calculated exactly. The calculation is not as straightforward as measuring a straight line because the cable hangs from poles. This results in a curved line, and using calculus takes that change into account.
Survey data is used in a number of different applications, including developing business plans. Surveys normally are made up of a variety of questions which result in a wide range of answers. By using calculus, all of these different variables are taken into account, which results in a more precise plan of action for the company.

Full Answer >Some examples of circles in real life are camera lenses, pizzas, tires, Ferris wheels, rings, steering wheels, cakes, pies, buttons and a satellite's orbit around the Earth. Circles are simply closed curves equidistant from a fixed center.
Full Answer >Because they are so closely related to exponential functions, logarithms have a number of applications in real life, especially when calculating the pH of any chemical substance or measuring the loudness of sounds through the use of decibels. Both of these activities, common in many different industries, require an understanding and application of logarithmic functions.
Full Answer >One common example of perpendicular lines in real life is the point where two city roads intersect. When one road crosses another, the two streets join at right angles to each other and form a cross-type pattern. Perpendicular lines form 90-degree angles, or right angles, to each other on a two-dimensional plane.
