SUMMARY
The discussion focuses on calculating the components of vectors u and v in vector calculus, specifically from the book "Div, Grad, Curl and All That." The user seeks clarification on how these components are derived, particularly on pages 14 and 15. The calculation of vector u is defined as a tangent vector, influenced by the surface's steepness, while vector v is orthogonal to u. The normal vector is determined by the cross product of u and v, emphasizing the importance of understanding the relationship between tangent vectors and their respective components in the x and y directions.
PREREQUISITES
