Ex 9.5, 18 The integrating Factor of the differential equation ๐ฅ ๐๐ฆ/๐๐ฅโ๐ฆ=2๐ฅ^2 is (A) ๐^(โ๐ฅ) (B) ๐^(โ๐ฆ) (C) 1/๐ฅ (D) ๐ฅ ๐ฅ ๐๐ฆ/๐๐ฅโ๐ฆ=2๐ฅ^2 Dividing both sides by x ๐ ๐/๐ ๐ โ ๐/๐ = 2x Differential equation in of the form ๐๐ฆ/๐๐ฅ + ๐๐ฆ = Q where P = (โ๐)/๐ & Q = 2x IF = ๐^โซ1โใ๐ ๐๐ฅใ IF = ๐^(โซ1โ(โ๐)/๐ ๐ ๐) IF = ๐^("โ" logโก๐ฅ ) IF = ๐^logโกใ๐ฅ^(โ1) ใ IF = xโ1 IF = ๐/๐ So, the correct answer is (c)
