Multicritical point

Saddle points

Just because the tangent plane to a multivariable function is flat, it doesn't mean that point is a local minimum or a local maximum. There is a third possibility, new to multivariable calculus, called a "saddle point".

Multivariable Maximum and Minimum Problems

In this video, we will work through several examples of problems where we find critical points of multivariable functions and test them to find local maximum and local minimum points.

Angle of Intersection Between Two Curves

Multivariable Calculus: Find the angle of intersection between the curves r1(t) = (1+t, t, t^3) and r2(t) = (cos(t), sin(t), t^2) at the point (1, 0, 0). For more videos like this one, please visit the Multivariable Calculus playlist at my channel.

Example of Vector Field

Multivariable Calculus: Sketch the vector field F(x, y) = ( y/sqrt(x^2+y^2), -x/sqrt(x^2+y^2) ) at the points (0,1), (4,3), (0,1), and (-3,4). We note some interesting properties of this vector field after switching to polar coordinates. For more videos like this one, please visit

Equation of a Plane Containing a Point and a Line

Multivariable Calculus: Find the equation of the plane containing the origin and the line r(t) = (2+3t, 4+t, 1+t). The key step involves using the cross product to find a normal vector. For more videos like this one, please visit the Multivariable Calculus playlist at my channel.
