[6.5] - Divergence / Curl : Visual
At the point indicated in each graph, estimate both the divergence (negative, postive, or zero) and the curl ($\uv k$ component: negative, positive, or 0).
top left: $\ \ \myv \grad \cdot \myv F = 0;\ \ \myv\grad\times \myv F = 0\ \ \ \ $ top right: $\ \ \myv \grad \cdot \myv F \gt 0;\ \ \myv\grad\times \myv F = 0$
bottom left: $\ \ \myv \grad \cdot \myv F \lt 0;\ \ \myv\grad\times \myv F = 0\ \ \ \ $
bottom right: $\ \ \myv \grad \cdot \myv F = 0;\ \ \myv\grad\times \myv F = \text{[negative number]}\uv k$
