Curated paths
Walk from a familiar starting point to a visual extension: stop at a high-school application, or keep going to a university concept.

From trigonometric functions to Fourier
Start from trigonometric functions on the unit circle and watch single sine waves add up to a wide range of periodic signals. The path begins with high-school trigonometry and ends at Fourier series, a university topic.

From plane vectors to three-dimensional geometry
Start from the basic operations on plane vectors and extend the dot product and projection to three dimensions. The cross product, normal vectors, and the distance from a point to a plane lead to a GSAT problem on distance in space.
