Dear Group,
any idea what is the problem with the output of this Manipulate?
Manipulate[
Plot3D[Sin[x]*Cos[y],{x,1,10},{y,2,10},RegionFunction->Function[{x,y},
45<=(y^x)]]
,{dummy,{True,False}}]
Interestingly none of the following codes produces errors:
Plot3D[Sin[x]*Cos[y], {x, 1, 10}, {y, 1, 10},
RegionFunction -> Function[{x, y}, 45 <= (y^x)]]
Manipulate[
Plot3D[Sin[x]*Cos[y], {x, 1, 10}, {y, 1, 10},
RegionFunction -> If[region, All, Function[{x, y}, 45 <= (y^x)]]]
, {region, {True, False}}]
Any suggestion would be appreciated.
Thanks in advance,
Istvan Zachar
