Until now, we have been viewing integrals as anti-derivatives. Now we explore them as the area under a curve between two boundaries (we will now construct definite integrals by defining the boundaries). This is the real meat of integral calculus!
This 16-minute video shows that the line integral of a scalar field is independent of path direction.
This 10-minute video lesson provides a second example of using path independence of a conservative vector field to solve a line integral.
In this tutorial, we will learn to approximate differentiable functions with polynomials. Beyond just being super cool, this can be useful for approximating functions so that they are easier to calculate, differentiate or integrate. So whether you will have to write simulations or become a bond trader (bond traders use polynomial approximation to estimate changes in bond prices given interest rate changes and vice versa), this tutorial could be fun. If that isn't motivation enough, we also come up with one of the most epic and powerful conclusions in all of mathematics in this tutorial: Euler's identity.
This 10-minute video lesson provides an introduction to the arithmetic and geometric series.
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.
