# What Kinds of Everyday Problems Can Be Solved Using Calculus?

## Introduction

Isaac Newton invented calculus before he turned 25, giving us a tool to send people to outer space, fight diseases, or solve financial problems. While we don’t use differentials and integrals on a daily basis, calculus is present in more daily activities than we know. In this article, we are going to share some of the most common practical applications of calculus in everyday life. It’s going to be both fun and educative to see all the amazing things we’re capable of thanks to this field of math.

## Engineering problems

Do you know how architects and civil engineers make buildings and bridges? To build a stable and safe structure, experts need to use multiple fields of science, and calculus is the main ingredient. Just like free online services help students find answers to complex calculus questions, this field of math helps architects solve questions of force distribution, necessary materials, or overall capacity for bridges, buildings, or roads. Integrals and differentials are tools that help determine the voltage and current intensity of capacitors.

Without calculus, engineers would have hard time building cars, rockets, or even gardening tools. Space engineering is only possible thanks to the principles of calculus that Sir Isaac Newton established centuries ago.

## Medicinal questions

When doctors wish to determine the rate of growth of certain bacteria, they use differential calculus. Doctors examine the growth of bacteria using different temperatures and food sources. The variations in temperatures and food sources help define their influence on the rate of growth of bacteria in a culture. Moreover, epidemiologists use calculus to determine the infection spread rate and geo-location. They also build safety measures and investigate sources of epidemics thanks to differential calculus.

Exponential equations help doctors with cancer treatment. This calculus principle allows the determination of cancer’s progression or regression. The doctors consider cancer cells’ size and number to determine if the tumor is advancing or receding. The application of calculus in medicine is extensive ranging from regular blood tests to calculating blood flow dynamics for building artificial aorta.

Doctors use calculus to control the volume of red blood cells during surgeries. Physicians introduce saline solutions during surgery according to calculations that this branch of mathematics provides.

## Finance and economic issues

It’s natural to expect that calculus plays a significant role in everyday financial problems. Did you ever wonder how much gas you need to cross a certain distance with your car? Calculus is what we use to determine the amount of gas we need per every 100 miles. Banks use calculus to settle your credit card payments. Variables such as interest rate and balance fluctuation are the main components of the payment structure.

Economists use calculus to understand the elasticity of supply and demand according to changes in price at a certain moment. This helps economists plan price changes or adapt to variations in supply and demand. When businessmen wish to increase revenue through production growth, calculus helps them reach the right answer. The same goes for production costs calculations. Different variables determine if the production costs increase or decrease based on the value of those variables.

## Analytics and statistics problems

Professionals use calculus to establish profitability, efficiency, or production rates in the manufacturing process. Different variables influence these results. Calculus allows us to predict processes using available data. Calculating a certain surface of the land is available through calculus. You can determine the average surface you cover while working or split the area of your home that you and your family members have to clean up.

When surveys have a wide range of potential answers, calculus allows us to predict the best course of action based on the provided answers. For those interested in demographics, calculus is a valuable tool. Through death and birth rates, we can apply calculus to determine changes in population growth.

## Conclusion

Since its inception, calculus raises questions and provides answers. Man past and present scholars argue that Leibniz is the father of calculus. Others say that both Newton and Leibniz came up with this discipline in their time of need. This branch of mathematics is essential for the modern-day lifestyle. We’re able to see, feel, and do many things thanks to the four principles of calculus. From space travel to credit card payments, calculus is with us every step of the way, every day.
