Question
**Problem Statement:**

Solve the initial value problem.

\[
(\tan(4y) - 1)dx + \left(4x \sec^2(4y) + \frac{1}{y}\right) dy = 0, \quad y(0) = 1
\]

**Provided Solution:**

The solution is:

\[ 
x \tan 4y + \ln |y| - k = 0 
\]

There is a note indicating that this solution is "wrong."

**Instruction:**

Type an equation using \(x\) and \(y\) as the variables. Type an implicit solution.

**Additional Notes:**

The problem requires solving a differential equation with given initial conditions. The provided solution marked "wrong" suggests there might be an error in the integration or substitution. Double-check calculations and substitutions before finalizing the solution.
