    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 2*sin(x)+3>z,2 is the coefficient of the function
    sin(x).
    Remember:
    Coefficient cannot change its value.
