` (i) if `x=t^2,y=t^3.`

The value of (d^(2)y)/(dx^(2)) at the point where t=0 is

If x = 2 cos t - cos 2t , y = 2 sin t - sin 2t , then the value of |(d^(2) y)/(dx^(2))|_(t= pi//2 ) is

If y=A sin(omega t-kx), then the value of (d^(2)y)/(dt^(2))/(d^(2)y)/(dx^(2))

If x = e^(t) sin t and y = e^(t) cos t, t is a parameter , then the value of (d^(2) x)/( dy^(2)) + (d^(2) y)/(dx^(2)) at t = 0 , is :

If x=cos t+(log tan t)/(2),y=sin t, then find the value of (d^(2)y)/(dt^(2)) and (d^(2)y)/(dx^(2)) at t=(pi)/(4)

If x=cos t+(log tan t)/(2),y=sin t, then find the value of (d^(2)y)/(dt^(2)) and (d^(2)y)/(dx^(2))a=(pi)/(4)

If x = 3 tan t and y = 3 sec t then the value of (d^2y)/(dx^2) at t = pi/4 , is 1/(ksqrt2) . The value of k is _________.
