If x=a(1- ), y=a( - ) , then d² y d x² =

Options

  1. A² ( 2 ) 2 acosec
  2. Bcosec 2 a ² ( 2 )
  3. C( 2 ) 2 asin
  4. D( 2 ) 2 a

Correct answer

B. cosec 2 a ² ( 2 )

Step-by-step solution

d x d =a , d y d =a(1- ) d y d x = a(1- ) a = 2 ² 2 2 2 2 = 2 d² y d x² = 1 2 ² 2 d d x = 1 2 ² 2 1 a = cosec 2 ² 2
