Evaluate ( ( k ) d k ) on ((0, ) )

Options

  1. A(2[ ( k )- k ( k )]+c )
  2. B(2[ ( k )+ k ( k )]+c )
  3. C(2[ k ( k )- k ( k )]+c )
  4. D(2[ ( k )- k ( k )]+c )

Correct answer

D. (2[ ( k )- k ( k )]+c )

Step-by-step solution

(I= ( k ) d k ) on (k (0, ) ) Put (k=t^2 d k=2 t d t ) ( aligned I & =2 t t d t & =-2 t t-2 1.(- t) d t (Integration by parts) aligned ) ( aligned & =-2 t t+2 t+c & =2[ ( k )- k ( k )]+c aligned )
