Question

if a+1/b varies inversely to a-1/b,prove that 'a' varies inversely as 'b'​

Answer 1

Answer:

Step-by-step explanation:

If (a+1/b) = 1/ (a-1/b)

or(a+1/b) * (a-1/b) = 1

or (a)2 - (1/b)2 = 1

or a2 = 1+ 1/b2

As 1 is a constant it implies that a2 varies inversely with b2

or a​varies inversely with b
