x के सापेक्ष `see (tan ^(-1)x ) ` का अवकल गुणांक ज्ञात कीजिए | |
|
Answer» माना ` " "y= sec (tan ^(-1)x)` माना ` tan ^(-1) x=t ` ` therefore " y= sec t ` या ` (dy)/(dx) =(d)/(dt) sect (dt)/(dx) =sec t tan t(d)/(dx) (tan ^(-1)x )` ` " " =(sec (tan ^(-1) x) tan (tan ^(-1)x ))/(1+ x^(2))` ` " "=(x)/( 1+x ^(2))sec(tan ^(-1) x )` |
