यदि y=tan (x+y), `(dy)/(dx)` निकालें।

लिखित उत्तर

Verified by Experts

दिया है ,`y=tan(x+y)`
x के सापेक्ष अवकलित करने पर हमें मिलता है,
`(dy)/(dx)=(d)/(d(x+y))tan(x+y)*(d)/(dx)(x+y)`
या `(dy)/(dx)=sec^(2)(x+y)(1+(dy)/(dx))`
या `(dy)/(dx)=sec^(2)(x+y)+sec^(2)(x+y)(dy)/(dx)`
या `[1-sec^(2)(x+y)](dy)/(dx)=sec^(2)(x+y)`
या `(dy)/(dx)=(sec^(2)(x+y))/(1-sec^(2)(x+y))=(1+y^(2))/(1-(1+y^(2)))=(1+y^(2))/(y^(2))[because(1)` से, y =tan (x+y)]
