Disk vs Washer vs Shell: When to Use Each Method

Perpendicular slices give disks and washers, parallel slices give shells — that one question picks the method. See one region solved all three ways, the radii for shifted axes, and a Pappus check that catches errors a re-run would miss.

How to Find the Pattern in a Number Sequence

Learn how to find the pattern in a number sequence using finite differences, ratio tests, and recursive rules — plus how to build the nth-term formula.

Line Integral vs Surface Integral: How to Set Up Each One

A line integral sums along a curve, a surface integral sums across a sheet. Here is how to parametrise each one, get the flux orientation right, and pick between Green’s, Stokes’ and the divergence theorem.
