If x denotes displacement in time t and x=a cost, then acceleration is :-

If the displacement at time 't' is x = acost, the acceleration is .......

If x = a cos t is the displacement in time t then, acceleration is :

If displacement x at time t is x = sqrt(1+ t^(2)) , then acceleration is

If displacement x at time t is x=sqrt(1+t^(2)) , then acceleration is
