Answer (Detailed Solution Below)
Detailed Solution
Download Solution PDFअवधारणा:
\(\rm \int \frac{1}{a^{2}+x^{2}}dx = \frac{1}{a}\tan ^{-1}\frac{x}{a}+ C\)
गणना:
दिया गया है : \(\rm dy = \left ( 4 + y^{2} \right )dx\)
⇒ \(\rm \frac{dy}{4+y^{2}}= dx\)
दोनों पक्षों का समाकलन करने पर, हमें मिलता है
\(\rm \int \frac{dy}{2^{2}+y^{2}}= \int dx\)
⇒ \(\rm \frac{1}{2}\tan^{-1}\frac{y}{2}= x+c\)
⇒ \(\rm \tan^{-1}\frac{y}{2}= 2x+ 2c\)
⇒ \(\rm \tan^{-1}\frac{y}{2}= 2x+ C\) [∵ 2c = C]
⇒ \(\rm \frac{y}{2}= \tan(2x+ C)\)
\(\rm y = 2\tan \left ( 2x+C \right )\)
सही विकल्प 2 है।
