PT Journal AU SMETANOVA, D VARGOVA, M Vladislav, B TI FUNCTION OF TWO VARIABLES IN 3D SO Trends in education PY 2016 BP 229 EP 233 VL 9 IS 1 DI 10.5507/tvv.2016.033 DE anaglyph; function of two variables; local extremes; saddle point; 3D AB Paper presents practical examples of utilising anaglyphic projection in support of student's better comprehension and visualisation of functions of two variables. Paper presents comparison of function graphical representation projected in flat surface and by anaglyphic projection. In support of better visualization, these figures were created for students of multivariable calculus. ER
