`(2-4t+5t^2)-(3t^2 + 2t -7)` is equivalent to :

If t+1/t =5, then (2t)/(3t^(2)-5t+3) is equal to ……..

If x=t^(2)andy=t^(3) , then (d^(2)y)/(dx^(2)) is equal to: a) (3)/(2) b) (3)/(2)t c) (3)/(2t) d) (3)/(4t)

If u = 3t^(4) - 5t^(3) + 2t^(2) - 18t+4 , find (du)/(dt) at t = 1 .

A function y=f(x) is given by x = phi (t)=t^(5)-5t^(3)-20t+7 y= Psi (t)=4t^(3)-3t^(2)-18t+3, -2 lt t lt 2 Find the maximum and minimum value of the function.

If the displacement of a particle is x=t^(3)-4t^(2)-5t , then the acceleration of particle at t=2 is

The displacement s of a particle at a time t is given bys =t^(3)-4t^(2)-5t. Find its velocity and acceleration at t=2 .

The displacement of a particle at time t is given by s= 2t^(3) -5t^(2)+ 4t-3 . Find the velocity when t = 2 sec.
