ListOfExpr is a list of right-hand sides that
define the system of ODEs (corresponds to
the order of dependent variables in
ListOfDepVars).
Var is the independent variable.
ListOfDepVars is a list of dependent
variables.
{Var0, VarMax} is a two-element list that
tells the function to integrate from Var0 to
VarMax.
ListOfDepVars0 is a list of initial values
for dependent variables.
VarStep is a nonzero number such that sign
(VarStep) = sign(VarMax-Var0) and
solutions are returned at Var0+i•VarStep
for all i=0,1,2,… such that Var0+i•VarStep
is in [var0,VarMax] (there may not be a
solution value at VarMax).
eulerStep is a positive integer (defaults to
1) that defines the number of euler steps
between output values. The actual step size
used by the euler method is
VarStep⁄ eulerStep.
System of equations:
withy1(0)=2 and y2(0)=5
eval () Hub Menu
eval(Expr) ⇒ string
eval() is valid only in the TI-Innovator™ Hub
Command argument of programming
commands Get, GetStr, and Send. The
software evaluates expression Expr and
replaces the eval() statement with the
result as a character string.
The argument Expr must simplify to a real
number.
Set the blue element of the RGB LED to half
intensity.
Reset the blue element to OFF.
eval() argument must simplify to a real
number.
