" 49.If "pv=81," then "(dp)/(dv)" at "v=9" is equal to "

If pv=81 then (dp)/(dv) at v=3 is

If 2t= v^(2) then (dv)/(dt) = …….

If v = log ( 1 + x^(2)) and u = x - tan^(-1) x then ,( du)/( dv) is equal to

If e^(v)+e^(u)=e^(v+u) , then (du)/(dv)=

Let v and a be the instantaneous velocity and acceleration of a particle moving in a plane. Then rate of change of speed (dv)/(dt) of the particle is equal to

Let v and a be the instantaneous velocity and acceleration of a particle moving in a plane. Then rate of change of speed (dv)/(dt) of the particle is equal to

Evaluate int (dv)/(1+2v)

If sqrt(u/v)+sqrt(v/u) =6 , then (du)/(dv) =

If p=9, v=3 , then find p is terms of v from the equation (dp)/(dv)=v+1/v^2

If p=9, v=3 , then find p is terms of v from the equation (dp)/(dv)=v+1/v^2
