If y= ( x) then d^2 y d x^2 =

Options

  1. Asech ^2 x
  2. B- sech ^2 x
  3. Cx
  4. D- x

Correct answer

A. sech ^2 x

Step-by-step solution

y= ( h x) Differentiating w.r.t. ' x ' on both sides aligned & d y d x = 1 x ( x) & d y d x = x aligned Again differentiating w.r.t. ' x ' on both sides d^2 y d x^2 = sech ^2 x Hence, option (1) is correct.
