Vector ►Polar
Note: You can insert this operator from the
computer keyboard by typing @>Polar.
Displays vector in polar form [r∠θ]. The
vector must be of dimension 2 and can be a
row or a column.
Note: ►Polar is a display-format
instruction, not a conversion function. You
can use it only at the end of an entry line,
and it does not update ans.
Note: See also ►Rect, page 144.
complexValue ►Polar
Displays complexVector in polar form.
• Degree angle mode returns (r∠θ).
• Radian angle mode returns re
i
θ
.
complexValue can have any complex form.
However, an re
i
θ
entry causes an error in
Degree angle mode.
Note: You must use the parentheses for an
(r∠θ) polar entry.
In Radian angle mode:
In Gradian angle mode:
In Degree angle mode:
polyCoeffs()
Catalog >
polyCoeffs(Poly [,Var]) ⇒ list
Returns a list of the coefficients of
polynomial Poly with respect to variable
Var.
Poly must be a polynomial expression in
Var. We recommend that you do not omit
Var unless Poly is an expression in a single
variable.
Expands the polynomial andselects x for the
omittedVar.
