Coefficient A constant multiplier of a variable is known as coefficient. They are typically represented by letters a,b,c. Example: In the expression 3x+5,3 is the coefficient of x. In the equation 4x+2y=6,4 is the coefficient of x and 2 is the coefficient of y. In the inequality 2sin+3z,2 is the coefficient of the function sin. Remember: Coefficient cannot change its value. 有一部分考生认为新GRE数学具有一定的难度，这其中的原因是由于考生在复习时没有把新GRE数学的基础打牢。想要新GRE数学考好，复习的时候一定要把基本概念和重要考点都弄扎实。祝大家都能取得理想成绩! |
