7. Tangent Lines, Normal Lines, and Tangent Planes

This is the seventh video in a series about multivariable functions. It is part of a series of videos covering topics in a typical Calculus 3 course.

This video covers the concepts of tangent lines, normal lines and tangent planes of multivariable functions including
- definition of tangent lines in the direction of x, in the direction of y and in the direction of u at a point on a surface
- computing tangent lines in specific directions at a point
- definition of the normal line at a point
- computing the normal line
- calculating a point of specified distance from a surface
- definition of the tangent plane at a point
- computing the tangent plane
- using a gradient of a three variable input function to compute the tangent plane
- using the gradient to compute the normal line
