Tue, 21 Oct 2014 06:31:05 +0000http://thecuriousastronomer.wordpress.com/?p=12324#comment-5036[…] In this blog, I used polar coordinates to derive the well-known expression for the area of a circle, . In today’s blog, I will go from 2 to 3-dimensions to derive the expression for the surface area of a sphere, which is . To do this, we need to use the 3-dimensional equivalent of polar coordinates, which are called spherical polar coordinates. […]

I actually did a post on my own blog, about a month ago, which also derived the formula for the Area of the Circle; however, I used a method from Geometry. Seeing a method from Calculus is one of those lovely ways we can see that mathematics always remains the same despite the fact that there are multiple methods in which to describe it!
