Question
Find \( dy/dx \) for \( x = 2t^2, y = 4t \).
Correct Answer
Option A is the correct answer.
Detailed Explanation
Parametric derivative: ( dy/dx = (dy/dt) / (dx/dt) ). ( dy/dt = 4 ), ( dx/dt = 4t ). So ( dy/dx = 4 / 4t = 1/t ).
Hint
Divide the derivative of \( y \) with respect to \( t \) by the derivative of \( x \) with respect to \( t \).
