Question
If y = (x + 
, then (1 + x2) 
is
, then (1 + x2) is Options
A.n2y
B.- n2y
C.- y
D.2x2y
Solution
y = (x + 
= n (x + 
n -1
or
Squaring, (1 + x2)y21 = n2y2
Differentiating, (1 + x2)2y1y2 + y12. 2x = n2 . 2yy1 (Here, y2 =
) or (1 + x2)y2 + xy1 = x2y
= n (x + n -1 or
Squaring, (1 + x2)y21 = n2y2Differentiating, (1 + x2)2y1y2 + y12. 2x = n2 . 2yy1 (Here, y2 =
) or (1 + x2)y2 + xy1 = x2yCreate a free account to view solution
