Sixteen-year-old Calissa Pham was scribbling equations in her school notebook when her math teacher paused mid-lecture. “Has anyone ever wondered if there might be other ways to prove the Pythagorean theorem?” the teacher asked casually. Most students shrugged, but Calissa’s hand shot up.
That simple question would eventually lead her and her classmate Ne’Kiya Jackson down a mathematical rabbit hole that would challenge 2,000 years of accepted mathematical wisdom. What started as teenage curiosity has now become one of the most significant mathematical breakthroughs in recent memory.
These two remarkable students from New Orleans have accomplished something that mathematicians once thought impossible—they’ve proven the Pythagorean theorem using trigonometry, without falling into the trap of circular reasoning that has stumped scholars for centuries.
What These Teenagers Actually Discovered
For over two millennia, mathematicians believed it was impossible to prove the Pythagorean theorem using trigonometry without creating what’s called “circular reasoning.” The problem was simple: trigonometry is built on the Pythagorean theorem, so using it to prove the theorem would be like trying to lift yourself up by your own shoelaces.
But Calissa and Ne’Kiya found a way around this logical trap. Working after school and during lunch breaks, they developed a proof using the Law of Sines that doesn’t rely on the Pythagorean theorem itself.
This is absolutely revolutionary. These students have opened a door that the mathematical community thought was permanently sealed shut.

Their discovery isn’t just academically impressive—it represents a fundamental shift in how we understand one of mathematics’ most basic principles. The Pythagorean theorem, which states that in a right triangle, the square of the longest side equals the sum of squares of the other two sides, now has a completely new type of proof.
What makes their achievement even more remarkable is that they didn’t stop at one proof. The teenagers have identified at least five different trigonometric methods that could potentially prove the theorem, suggesting there might be an entire family of proofs waiting to be discovered.
Breaking Down Their Mathematical Breakthrough
The technical details of their proof involve sophisticated mathematical concepts, but here’s what makes their approach so groundbreaking:
| Traditional Approach | Pham-Jackson Method |
|---|---|
| Uses geometric principles | Uses trigonometric relationships |
| Relies on visual proofs | Uses algebraic manipulation |
| Limited to known methods | Opens new proof possibilities |
| Circular reasoning problems | Avoids logical contradictions |
Their proof works by using the Law of Sines in a way that creates what mathematicians call an “infinite geometric series.” This series converges to prove the Pythagorean relationship without ever needing to assume the theorem is true in the first place.
- They start with a right triangle and create an infinite sequence of similar triangles
- Each triangle in the sequence gets progressively smaller
- Using trigonometric ratios, they show this sequence converges to the Pythagorean relationship
- The proof never assumes what it’s trying to prove, avoiding circular reasoning
What impressed me most wasn’t just their mathematical skill, but their persistence. They spent months working through problems that have stumped professional mathematicians.
— Michelle Blouin, High School Mathematics Teacher
The mathematical community has been buzzing about their work since it was first presented at a professional conference. Peer reviewers have confirmed the validity of their approach, and their research has been published in academic journals—an extremely rare achievement for high school students.
Why This Discovery Matters Beyond Mathematics
This breakthrough extends far beyond academic mathematics. The students’ success challenges fundamental assumptions about mathematical education and what young minds can achieve when given the right encouragement and resources.
Their discovery has practical implications for how trigonometry and geometry are taught in schools. Teachers now have new tools to help students understand these concepts, and the proof provides fresh perspectives on mathematical relationships that seemed completely settled.
This shows that innovation can come from anywhere. These students weren’t constrained by decades of mathematical tradition telling them something was impossible.

The impact goes beyond mathematics education. Their work demonstrates the importance of encouraging student curiosity and providing opportunities for young people to engage in serious research. Both students credit their teachers and school environment for supporting their unconventional approach to the problem.
From a broader perspective, their achievement highlights how fresh eyes can see solutions that experts might miss. The mathematical community’s excitement about their work reflects not just the technical merit of their proof, but the inspiration it provides for future mathematical exploration.
Universities across the country have taken notice, with several institutions already reaching out to both students about potential scholarship opportunities and research collaborations.
These young women have reminded us all that mathematics is still full of surprises, even in areas we thought we completely understood.

Their success also represents an important moment for diversity in mathematics. Both students bring perspectives that have been historically underrepresented in mathematical research, and their achievement may inspire other young people from similar backgrounds to pursue mathematical careers.
The ripple effects of their discovery continue to spread through academic circles, with mathematicians now investigating whether similar approaches might work for other fundamental theorems. Their work has essentially created a new research direction that could keep mathematicians busy for years to come.
FAQs
How long did it take them to develop this proof?
The students worked on their proof for several months, spending countless hours after school and during breaks refining their approach.
Will this change how math is taught in schools?
Their discovery provides new teaching tools, but it will likely supplement rather than replace traditional methods of teaching the Pythagorean theorem.
Have other students ever made similar mathematical discoveries?
While students occasionally contribute to mathematical research, proving a fundamental theorem in a completely new way is extremely rare at the high school level.
What are the students planning to study in college?
Both students are considering mathematics-related fields, though they’re also exploring other interests including engineering and computer science.
Could there be more trigonometric proofs of the Pythagorean theorem?
Yes, the students identified at least five potential methods, suggesting this might be just the beginning of a new area of mathematical research.
How has the mathematical community responded to their work?
Professional mathematicians have been overwhelmingly positive, with many expressing amazement that high school students tackled and solved such a challenging problem.
