sum(list[,start,end])
-vMATH
Returns the sum of all elements in list. Specify the
additional optional arguments to return the sum of the
range of elements between start and end.

tan(value)
-uTRIG
Returns the tangent of a real number, expression, or
all elements in a list. Results are determined by the
Angle mode setting (Degree or Radian).
In Degree mode:
tan(0)
b0
tan({0,1,30})
b
{0 .0174550649 .5773502692}
In Radian mode:
tan(p/4) b1
tan({p/2,p/4,0}) b
{1 0 0}
tanL1(value)
-uTRIG
Returns the arctangent of a real number, expression,
or each element in a list.
Since tan=sinàcos, tan is undefined when cos=0.
Results are determined by the Angle mode setting
(Degree or Radian).
In Degree mode:
tan (1) b45
tan ({.5,1,0)) b
{26.56505118 45 0}
In Radian mode:
tan (.5) b.463647609
tan ({.5,1,0)) b
{.463647609 .7853981634 0}
