# 10 Free Online Courses To Supplement Your Calculus Skills

Blog

Take free online calculus courses to build your math skills and improve your performance in school and at work.  Here are the top 10 online courses to supplement your calculus skills:

1. Calculus 1C: Coordinate Systems & Infinite Series

How did Newton describe the orbits of the planets? To do this, he created calculus. But he used a different coordinate system more appropriate for planetary motion. We will learn to shift our perspective to do calculus with parameterized curves and polar coordinates. And then we will dive deep into exploring the infinite to gain a deeper understanding and powerful descriptions of functions.

How does a computer make accurate computations? Absolute precision does not exist in the real world, and computers cannot handle infinitesimals or infinity. Fortunately, just as we approximate numbers using the decimal system, we can approximate functions using series of much simpler functions. These approximations provide a powerful framework for scientific computing and still give highly accurate results. They allow us to solve all sorts of engineering problems based on models of our world represented in the language of calculus.

1. Changing Perspectives
1. Parametric Equations
2. Polar Coordinates
2. Series and Polynomial Approximations
1. Series and Convergence
2. Taylor Series and Power Series

##### What you’ll learn
• To compute arc length
• Methods for parameterizing curves

3. Calculus Applied

In this course, we go beyond the calculus textbook, working with practitioners in social, life and physical sciences to understand how calculus and mathematical models play a role in their work.

This is a course to learn applications of calculus to other fields, and NOT a course to learn the basics of calculus. Whether you’re a student who has just finished an introductory Calculus course or a teacher looking for more authentic examples for your classroom, there is something for you to learn here, and we hope you’ll join us!

##### What you’ll learn
• Authentic examples and case studies of how calculus is applied to problems in other fields
• How to analyze mathematical models, including variables, constants, and parameters
• Appreciation for the assumptions and complications that go into modeling real world situations with mathematics

Length: 10 weeks

Level: Intermediate

4. Engineering Calculus and Differential Equations

How do electrical engineers find out all the currents and voltages in a network of connected components? How do civil engineers calculate the materials necessary to construct a curved dome over a new sports arena? How do space flight engineers launch an exploratory probe? If questions like these pique your interest, this course is for you!

This course will enable you to develop a more profound understanding of engineering concepts and enhance your skills in solving engineering problems. In other words, youwill be able to construct relatively simple models of change and deduce their consequences. By studying these, youwill learn how to monitor and even controla given system to do what you want it to do.

Techniques widely used in engineering will be illustrated; such as Laplace transform for solving problems in vibrations and signal processing. We have designed animations and interactive visualizations to supplement complex mathematical theories and facilitate understanding of the dynamic nature of topics involving calculus.

##### What you’ll learn
• Limits, Continuity, and Differentiation in Engineering Calculus
• Applications of Derivatives
• Parametric Equations and Polar Coordinates
• Techniques of Integration
• Applications of Definite Integrals
• Engineering Differential Equations and First Order Equations
• Homogeneous, Inhomogeneous Equations, and Exact Equations
• Homogeneous Linear Equations with Constant Coefficients

• How to analyze a given engineering problem
• Ways to identify appropriate calculus and ordinary differential equations (ODE) skills
• How to formulate the mathematical problem
• How to find the solutions for engineering problems

5. Introduction to Calculus

The focus and themes of the Introduction to Calculus course address the most important foundations for applications of mathematics in science, engineering and commerce. The course emphasizes the key ideas and historical motivation for calculus, while at the same time striking a balance between theory and application, leading to a mastery of key threshold concepts in foundational mathematics.

Students taking Introduction to Calculus will:

•  gain familiarity with key ideas of precalculus, including the manipulation of equations and elementary functions (first two weeks),

• develop fluency with the preliminary methodology of tangents and limits, and the definition of a derivative (third week),

• develop and practice methods of differential calculus with applications (fourth week),

• develop and practice methods of the integral calculus (fifth week).

6. Calculus: Single Variable Part 1 – Functions

Calculus is one of the grandest achievements of human thought, explaining everything from planetary orbits to the optimal size of a city to the periodicity of a heartbeat. This brisk course covers the core ideas of single-variable Calculus with emphases on conceptual understanding and applications. The course is ideal for students beginning in the engineering, physical, and social sciences. Distinguishing features of the course include: 1) the introduction and use of Taylor series and approximations from the beginning; 2) a novel synthesis of discrete and continuous forms of Calculus; 3) an emphasis on the conceptual over the computational; and 4) a clear, dynamic, unified approach.

In this first part–part one of five–you will extend your understanding of Taylor series, review limits, learn the *why* behind l’Hopital’s rule, and, most importantly, learn a new language for describing growth and decay of functions: the BIG O.
