Purely algebraic. 'x-1' is a factor of 'x^n - 1'. Divide and conquer.zgall1 said:lim x --> 1 (x^n - 1)/(x-1)
You must be "plugging" incorrectly . . .]When I plugged in various values for n, I found that as x --> 1, y approaches infinity . ?
But with the method described above, the limit = 0 . ?
Where am I going wrong? . . . everywhere!
