Exponent

Usage

Exponent[expr, form] 用来给出expr展开式中form 的最大幂.
Exponent[expr, form, h]h 应用到exprform 的指数集上.


Notes

• 例如: Exponent[x^2 + a x^3, x]LongRightArrow .
h 的缺省值为 Max.
• 例如: Exponent[x^2 + a x^3, x, List]LongRightArrow .
form 可以是项的乘积.
• 无论是否明确给出展开式,Exponent 都会起作用.
• 参见Mathematica 全书: 1.4.7节3.3.2节.
• 同时参见: Coefficient, Cases, IntegerExponent.
Further Examples

Exponent gives its second argument's highest power in the polynomial.

In[1]:=  

Out[1]=

In[2]:=  

Out[2]=

In[3]:=  

Out[3]=

With List as the third argument you get a list of all the exponents.

In[4]:=  

Out[4]=
