1. Assume that x and y are both differentiable functions of t and find the required values of (dy/dt) and (dx/dt).
Equation ---> xy = 4
find (dy/dt) when x = 8
Given (dx/dt) = 10
i tried to find the derivative of xy = 4
x(dy/dt) + y(dx/dt) = 0
and then i just plugged in the values but that gave me -(10y/8)
and the answers is -(5/8)
