n = 1: activate window 1, return previous active
window number.
n = 2: activate window 2, return previous active
window number.
(transpose)
matrix
Return complex conjugate transpose of matrix.
Table expr1[,expr2][,var]
Build a table of the argument expression(s) or
functions. The current Y= Editor functions are
temporarily ignored. Expressions entered with
Table or Graph are assigned increasing function
numbers beginning with 1. To clear these
functions execute ClrGraph or display the Y=
Editor. If var is omitted, the current graph mode
independent variable is used. Table cannot be
used with 3D, sequence or differential equations
graphing. Valid variations are:
Function graph: Table expr,x
Parametric graph: Table xExpr,yExpr,t
Polar graph: Table expr, θ

tan()
(expr), (list)
Return the tangent of the argument. The
argument is interpreted in degrees or radians
according to the current mode setting. Use ° or
to override the mode setting.
(matrix)
Return the matrix tangent of square matrix,
which is not the tangent of each element. Refer
to cos() for details. matrix must be
diagonalizable and the result always constains
floating-point numbers.
tan
-1
()
(expr), (list)
Return the angle whose tangent is the
argument. The result is returned as degrees or
radians depending on the current Angle mode
setting.
(matrix)
Return the matrix inverse tangent of square
matrix, which is not the same as the inverse
tangent of each element. Refer to cos() for
details. matrix must be diagonalizable and the
result always constains floating-point numbers.
tanh()
(expr), (list)
Return the hyperbolic tangent of the argument.
The argument is interpreted in degrees or
radians according to the current mode setting.
Use ° or to override the mode setting.
(matrix)
Return the matrix hyperbolic tangent of square
matrix, which is not the hyperbolic tangent of
each element. Refer to cos() for details. matrix
must be diagonalizable and the result always
constains floating-point numbers
tanh
-1
()
(expr), (list)
Return the angle whose hyperbolic tangent is
the argument. The result is returned as degrees
or radians depending on the current Angle mode
setting.
(matrix)
Return the matrix inverse hyperbolic tangent of
square matrix, which is not the same as the
inverse hyperbolic tangent of each element.
Refer to cos() for details. matrix must be
diagonalizable and the result always constains
floating-point numbers.
taylor(expr,var,order[,point])
Return the Taylor polynomial for expr in var.
point is the expansion point and defaults to zero.
The polynomial includes non-zero terms of
integer degree from 0 through order in (var -
point). taylor() returns itself if there is not
truncated power series of this order, or negative
or fractional exponents are required. Use
substitution or temporary multiplication by a
power of (var - point) for a more general series.
tCollect(expr)
Return expression in which products and integer
powers of sines and cosines are converted to a
linear combination of sines and cosines of
multiple arguments, angle sums and angle
differences. Trigonometric polynomials are
converted to linear combinations of harmonics.
tCollect() tends to reverse tExpand(). Applying
tExpand() to a tCollect() result, or vice versa, in
two steps may simplify an expression.
tExpand(expr)
Return expression in which sines and cosines of
integer-multiple angles, angle sums and angle
