##

Trailing coefficient degree of a polynomial : `tcoeff`

`tcoeff` takes as argument a polynomial given by a
symbolic expression
or by the list of its coefficients.

`tcoeff` returns the coefficient of the monomial of lowest degree
of this polynomial (`tcoeff`=trailing coefficient).

Input :
`tcoeff([2,1,-1,0])`

Output :
`-1`

Input :
`tcoeff(3*x``^`

2+5*x,x)

Output :
`5`

Input :
`tcoeff(3*x``^`

2+5*x*y`^`

2,y)

Output :
`3*x``^`
