  Choosing the Right Perspective: Why Problem Setup Matters More Than the Math
  Last Updated on October 18, 2025 by Rajeev Bagra In calculus, it’s fascinating that the disk and shell methods both yield the same volume for a solid of revolution. Yet in practice, one can make your work smooth and elegant—while the other can make it messy. Take the witches’ kettle example. The temperature inside the… Read more: Choosing the Right Perspective: Why Problem Setup Matters More Than the Math
