Question

If x and y are connected parametrically by the equations, without eliminating the parameter, find `bb(dy/dx)`.

x = 4t, y = `4/y`

Sum

Solution

Given, x = 4t and y = `4/t`

Differentiating both sides with respect to t,

`dx/dt` = 4 and `dy/dt = (-4)/t^2`

Hence, `dy/dx = (dy/dt)/(dx/dt)`

= `((-4)/t^2)/4`

= `(- 1)/t^2`
