Chapter 2: Q. 75 (page 211)

Each of the equations in Exercises 69鈥�80 defines y as an implicit function of x. Use implicit differentiation (without solving for y first) to find $\frac{d y}{d x}$
$\sqrt{3 y - 1} = 5 x y$

Short Answer

Expert verified

$\frac{d y}{d x} = \frac{10 y \sqrt{3 y - 1}}{3 - 10 x \sqrt{3 y - 1}}$

Step by step solution

Step 1. Given Information:

Given equation: $\sqrt{3 y - 1} = 5 x y$

We want to find $\frac{d y}{d x}$ defines y as an implicit function of x by use implicit differentiation.

Step 2. Solution:

Differentiate both sides w.r.t. x

$\frac{d}{d x} \sqrt{3 y - 1} = \frac{d}{d x} (5 x y) \frac{d}{d x} {(3 y - 1)}^{\frac{1}{2}} = \frac{d}{d x} (5 x y)$

Using product and chain rule we get

$\frac{1}{2} {(3 y - 1)}^{\frac{1}{2} - 1} \frac{d}{d x} (3 y - 1) = 5 x \frac{d}{d x} y + 5 y \frac{d}{d x} x \frac{1}{2 \sqrt{3 y - 1}} (3 \frac{d y}{d x}) = 5 x \frac{d y}{d x} + 5 y \frac{3}{2 \sqrt{3 y - 1}} \frac{d y}{d x} - 5 x \frac{d y}{d x} = 5 y (\frac{3}{2 \sqrt{3 y - 1}} - 5 x) \frac{d y}{d x} = 5 y (\frac{3 - 10 x \sqrt{3 y - 1}}{2 \sqrt{3 y - 1}}) \frac{d y}{d x} = 5 y \frac{d y}{d x} = \frac{10 y \sqrt{3 y - 1}}{3 - 10 x \sqrt{3 y - 1}}$
