Part 4: How to Actually "Read" a Math PDF
Reading math on a screen is cognitively harder than on paper. Here is a workflow for the Wazwaz PDF:
- The Two-Screen Setup: Open the PDF on one screen. Open a digital whiteboard (or a notebook) on the other. Do not just read the examples. Wazwaz skips intermediate algebraic steps. You must fill them in.
- Identify the "Kernel": In every problem, identify the kernel $K(x,t)$. Circle it. The behavior of the kernel dictates the method of solution.
- The "Red Pen" Method: If you are using a tablet, highlight every instance of the series solution. Wazwaz loves expressing answers as infinite series $u(x) = \sum u_n(x)$. If you can write the first three terms of this series, you have solved the problem.
Understanding Integral Equations
Integral equations are equations in which an unknown function appears under an integral sign. They are often used to solve problems that involve physical phenomena such as heat transfer, vibrations, and fluid dynamics.
