# Ch 14: Partial Derivatives

Getting a clear idea of how to work with functions of multiple variables in calculus can be a breeze when you watch these videos. Test your skills working with first- and higher-order derivatives by taking the quizzes and exam in this chapter.

## Partial Derivatives - Chapter Summary

Spend a little time with these video lessons to learn about the infinite points of change that exist when dealing with more than one variable in a function and why this scenario makes it tough to take a derivative at any given point. The video lessons in this chapter can help you understand how to take derivatives of complex functions one variable at a time.

Our expert instructors first define partial variables and show you how to represent partial derivatives of functions with respect to x and to y. They build on that base with a discussion on finding derivatives of second order and higher. The chapter closes with lessons on the chain rule and directional derivatives. The topics in this chapter cover:

• How to solve equations with partial derivatives
• Representing partial derivatives geometrically
• How to solve higher-order partial derivatives
• Obtaining tangent planes to a surface
• Using the chain rule with partial derivatives
• Working with directional derivatives, including gradient of f and min/max

Each of these videos explains the process of solving partial derivative equations using real-world examples in under 10 minutes each. Our instructors are all experienced math professionals and teachers and they present the lessons with entertaining graphics for a memorable visual experience. Use the lesson transcripts for follow-up study and take the self-assessments to measure your understanding of the concepts.
