It is important to remember that expressions for the operations of vector analysis are different in di64256erent coordinates Here we give explicit formulae for cylindrical and spherical coordinates 1 Cylindrical Coordinates In cylindrical coordinate. So if PQR then div 8711 8706x 8706y 8706z PQR 8706P 8706x 8706Q 8706y 8706R 8706z Notice that div is a scalar Find div for each of the following vector 64257elds i xyyzxz ii yzxzxy iii where iv grad where is a function with continuous second der r.
