If `y=sin(t^2)`, then `(d^2y)/(dt^2)` will be

If y=A sin 5x, then (d^2y)/(dx^2) =

If y = sin3x then (d^2y)/(dx^2) =?

If x= sin t and y= sin^(3)t , then (d^(2)y)/(dx^(2)) at t=pi/2 is

If x=3 cos t and y=4 sin t , then (d^2y)/(dx^2) at the point (x_0,y_0)=(3/2sqrt2,2sqrt2) ,is

If x=tlogt,y=t^(t)," then "(d^2y)/(dx^(2))=

If y is displacement and t is time, unit of (d^(2)y)/(dt^(2)) will be

If sin y=x sin(a+y), then (dy)/(dx) is (a) (sin a)/(sin a sin^(2)(a+y))(b)(s in^(2)(a+y))/(sin a)(c)sin a sin^(2)(a+y)(d)(sin^(2)(a-y))/(sin a)
