In a remote region of the Amazon rainforest, a team of biologists, led by Dr. Maria Rodriguez, had been studying a rare and exotic species of butterfly, known as the "Moonlight Serenade." This species was characterized by its iridescent wings, which shimmered in the moonlight, and its unique mating rituals, which involved a complex dance of lights and sounds.

In many editions, critical formulas (like the integrating factor e^(∫P dx) or the Wronskian) are placed in highlighted boxes. Create a separate "Formula Register" with pages noted from Ahsan.
