This 10-minute video lesson looks at finding the sum of an infinite geometric series.
This 10-minute video lesson take the revolution around something other than one of the axes.
This 4-minute video lesson looks at the last part of the problem in part 7 (see previous video lesson).
This video looks at the example showing how to find the volume of a solid of revolution (constructed by rotating around the x-axis) using the shell method (this could have been done with the disk method as well).
You want to rotate a function around a vertical line, but do all your integrating in terms of x and f(x), then the shell method is your new friend. It is similarly fantastic when you want to rotate around a horizontal line but integrate in terms of y.
This 9-minute video lesson uses the \shell method\ to rotate about the y-axis.
This video covers using the shell method to rotate around a vertical line.
This video looks at the shell method with two functions of y.
This video looks at showing explicit and implicit differentiation give same result.
In this tutorial, we'll think about how we can find the area under a curve. We'll first approximate this with rectangles (and trapezoids)--generally called Riemann sums. We'll then think about find the exact area by having the number of rectangles approach infinity (they'll have infinitesimal widths) which we'll use the definite integral to denote.
This 7-minute video lesson examines the Sine Taylor Series at 0 (Maclaurin).
This 16-minute video lesson covers the Calculus-Derivative: Understanding that the derivative is just the slope of a curve at a point (or the slope of the tangent line).
This video looks at the speed of shadow of diving bird.
If a function is always smaller than one function and always greater than another (i.e. it is always between them), then if the upper and lower function converge to a limit at a point, then so does the one in between. Not only is this useful for proving certain tricky limits (we use it to prove lim (x _ 0) of (sin x)/x, but it is a useful metaphor to use in life (seriously). :) This tutorial is useful but optional. It is covered in most calculus courses, but it is not necessary to progress on to the "Introduction to derivatives" tutorial.
This video looks at starting to apply stokes theorem to solve a line integral.
This video looks at converting the surface integral to a double integral.
This video looks at Finding the curl of the vector field and then evaluating the double integral in the parameter domain.
Stokes' theorem relates the line integral around a surface to the curl on the surface. This tutorial explores the intuition behind Stokes' theorem, how it is an extension of Green's theorem to surfaces (as opposed to just regions) and gives some examples using it. We prove Stokes' theorem in another tutorial. Good to come to this tutorial having experienced the tutorial on "flux in 3D".
This video covers The beginning of a proof of stokes' theorem for a special class of surfaces. Finding the curl of our vector field.
This video looks at Figuring out a parameterization of our surface and representing ds.
