【金-元】元好问

绿叶阴浓，遍池亭水阁，偏趁凉多。海榴初绽，朵朵簇红罗。乳燕雏莺弄语，有高柳鸣蝉相和。骤雨过，似琼珠乱撒，打遍新荷。

人生百年有几，念良辰美景，休放虚过。穷通前定，何用苦张罗。命友邀宾玩赏，对芳樽浅酌低歌。且酩酊，任他两轮日月，来往如梭。

【金-元】元好问

重冈已隔红尘断，村落更年丰。移居要就，窗中远岫，舍后长松。 十年种木，一年种谷，都付儿童。老夫惟有，醒来明月，醉后清风。

This note explains how infinitesimal changes transform under coordinate maps via the Jacobian matrix—from differential displacement to differential area and volume—in Cartesian, cylindrical, and spherical coordinates.

Note: Everything here is 3D and the cross product is used. In general dimensions, area/volume elements are best expressed using differential forms (wedge products); the 3D vector formulas here are a special case.
