Question

If x=at^2 and y=2at then dy/dx =? Plz solve

Answer 1

dx/dt=2at
dy/dt=2a
dy/dx=(dy/dt)/(dx/dt)=2a/(2at)=1/t

Answer 2

dy/dx = 2a/2at=1/t

Answer 3

Firstly calculate for dx/dt = 2at ---------1
And dy/dt = 2a ----------------2

Just divide 2 by 1:

dy/dx = 2a/2at

dy/dx = 1/t is the answer...
