PT Journal AU LISKA, V TI TRANSFORMATION THREE-DIMENSIONAL INTEGRALS SO Trends in education PY 2011 BP 112 EP 115 VL 4 IS 1 DE three-dimensional integral; Theorem of Fubini; cylindrical coordinates. AB Substitution Method to multidimensional integrals is a powerful tool for calculating them, but its routine application can lead to lengthy calculations. This fact presents the example of three-dimensional integral, where the fundamental field is cone with its axis of symmetry o z . ER
