संकल्पना:

समाकलन कारक, (IF) अवकल समीकरण, dxdy+Px=Q, के लिए जहां P और Q को y का सतत फलन दिया जाता है।

 IF = ePdy

गणना:

दिए गए समीकरण को निम्न प्रकार सरल बनाया जा सकता है,

dxdy+x2y=52y

मानक समीकरण dxdy+Px=Qके साथ समीकरणों की तुलना करने पर, हम प्राप्त करते हैं,

P = 12y और Q = 52y

 ∴ IF = ePdy = e12ydy

⇒ IF = e12logy = elogy12

IF = y .  (∵ ealogx=xa)

सही विकल्प 1 है।
