Question

x = 4t, y = 4/t dy/dx find dy/dx

Answer 1

Answer:

x =4t

dx/dt =4

y =4/t

dy/dt =-4/t^2

dy/dx= dy/dt×dt/dx

=-4/t^2×1/4

= -1/t^2

Answer 2

dy/dx = -1/t² , x = 4t, y = 4/t

Step-by-step explanation:

dy/dx

x =4t

y = 4/t

x =4t

dx/dt  = 4

y = 4/t

dy/dt  = -4/t²

(dy/dt)/(dx/dt)  =   (-4/t²) / 4

=> dy/dx = -1/t²
