In this video I go over Part 3 of the surface area for parametric curves videos series, and this time extend the formula derived in Parts 1 and 2 even further. The formula derived was for determining the surface area of a shape formed by rotating the parametric curve about the x-axis, but in this video I show that it is in fact similar for if it’s rotated about the y-axis. The only thing that changes is the “radius” of a segment being rotated becomes “x” as opposed to “y”. I also I show that the symbolic representation of the surface area is the same as that for surface area of a regular function, and similar to the arc length formula, which I have covered in earlier videos. Basically we can replace the arc length segment thickness with “ds”. I show the visual representation of this term and corresponding formulas for the shapes formed by rotating by the x and y-axis. This is a great video to get a better understanding of just how the surface area formula is visually represented which helps in memorizing how to apply this formula, so make sure to watch this video!
