In a quiet little town called Numeroville, seven mathematical symbols lived together, each with their
distinct personalities and roles. There was the charismatic Sigma \(( \sum ) \), the versatile Pi \((
\pi ) \), the stern Integer \( (Z) \), the cryptic Imaginary Unit \( (i) \), the elegant Infinity \(
\infty \), the daring Differential \((dx)\), and the unassuming Constant \((C)\).

One fateful
evening, the town was shocked to find the lifeless body of Constant, lying motionless in the Town
Square. The distraught symbols gathered around, unable to make sense of the tragedy. It was then that
Sigma, the town's trusted detective, stepped in to solve the mystery of the collapsed Constant.

As the investigation began, Sigma first turned to Integer, known for being disciplined and orderly.
Integer was often responsible for organizing events in Numeroville. Sigma questioned Integer about the
evening's events, but Integer insisted he had been arranging a number-theoretic gathering all night and
had no knowledge of what had transpired.

Next, Sigma sought out Pi, the symbol of infinite
possibilities. Pi was known for its endless decimal expansion and being hard to pin down. Sigma asked Pi
about its whereabouts at the time of the incident, but Pi could only offer a vague, non-repeating
answer, claiming to have been exploring circles in a nearby park.

Determined to get to the
bottom of the case, Sigma approached Imaginary Unit, the enigmatic symbol who always seemed to exist in
a different plane altogether. Upon inquiry, Imaginary Unit claimed to have been attending a complex
function party, far from the scene of the crime.

The detective then turned to Infinity, the
boundless, free-spirited symbol. Infinity said it had been contemplating the vastness of the universe at
the time, and while it was hard to be certain, it didn't think it had been anywhere near the Town
Square.

Growing more frustrated, Sigma decided to consult with Differential, the ever-changing
and dynamic symbol. Differential claimed to have been examining the delicate slopes of Numeroville's
hills during the incident, always on the move, and could not have been involved.

Sigma, now
feeling the weight of the investigation, realized the importance of examining the relationships between
the symbols. It was then that he discovered a crucial piece of evidence: Differential and Constant had a
tumultuous history, with Constant often feeling overshadowed by Differential's prominence in the world
of calculus.

With this new information in hand, Sigma confronted Differential, who ultimately
confessed to the crime. Overcome by jealousy and ambition, Differential had sought to eliminate the
competition and become the sole representative of calculus in Numeroville. Ashamed of its actions,
Differential was taken into custody, and justice was finally served.

In the end, Sigma's keen
eye for detail and ability to synthesize information from multiple sources helped uncover the truth
behind the mysterious death of Constant. The symbols of Numeroville were grateful for Sigma's dedication
and skill, and their trust in him only grew stronger. Life eventually returned to normal, but the memory
of Constant's untimely demise served as a reminder to all that even in the orderly world of mathematics,
chaos and envy could still find a way to disrupt the balance.
