L£t z. = becaufe in this Cafe r — i, 

 0 = 0, therefore the Term laft breaking off 



is r 4— f whence + ? = ~ (by 



n-\~2%n-\-\\ 



a ,

the laft Term to be multiplied into \Jzay—y % i 

 therefore ABD = vy -f *- + V lay + y % x

Let ^ — 2? ■ becaufe in this Cafe r = ~, 

 n == i, therefore the Term laft breaking off 



is 1 z y = — , whence ^, 



and i * is the laft Term to be multiplied by 



V ^ 2ay-\-y 7 \ therefore
