alnertia
(density, var1, lower1, upper1, var2, lower2(var1), upper2(var1))
Returns a 2x2 matrix denoting the inertia tensor of a density
over a two-dimensional region.
var1
varies from
lower1
to
upper1
, which must be independent of
var1
and
var2
.
var2
varies
from expression
lower2
to expression
upper2
, which might
depend on
var1
. Use
density
1 for an area inertia tensor.
Use F6 7:Inertia Tensor to display the problem-entry dialog
box and example for this function.
cntrCurv
(expression, var)
Returns a two-element list that is a parametric representation
of the center of curvature of
expression
with respect to
var
.
Use F2 6:Center of Curvature
to display the problem-entry
dialog box and example for this function.
curl
(exprList, xVar, yVar, zVar)
Returns the three-dimensional rectangular Cartesian curl of
the vector represented by
exprList
with respect to the
coordinate variables
xVar, yVar, zVar
.
Use F5 3:Curl to display the problem-entry dialog box and
example for this function.
