Fig. 3 shows a few such curves (n = 0, 1, 2). To the right of such curves 

 the individual term in question is negative, except on the Hne, k^ = 

 {n + V^) , where it attains the value of zero. Approaching the curves 

 from the right the terms go to — oo . On the left of the curves the func- 

 tion is positive and goes to + oo as the curve is approached from the
