DEG INDEX

DEG _ _ _ _ _ _ _ _ _ _ _ _ operator

The operator deg returns the highest degree of its variable argument found in its expression argument.

syntax:

deg(<expression>,<kernel>)

<expression> is expected to be a polynomial expression, not a rational expression. Rational expressions are accepted when the switch ratarg is on. <variable> must be a kernel. The results are returned in a list.

examples:



deg((x+y)**5,x); 

  5 



deg((a+b)*(c+2*d)**2,d); 

  2 



deg(x**2 + cos(y),sin(x)); 


deg((x**2 + sin(x))**5,sin(x)); 

  5
