I’m in a season of life when more of my former teachers are passing away, each loss reminding me how early mentors helped lead me to the right place. All of this came to mind recently with the news ...

This is an updated version of a story first published on May 5, 2024. For many high school students returning to class, it may seem like geometry and trigonometry were created by the Greeks as a form ...

P.S.—Since the above was written, I have had time to reflect further upon Prof. Hatton's book, and have read Prof. G. H. Hardy's review of in a recent number of the Mathematical Gazette. I do not ...

THIS is a sequel to the large “Plane Trigonometry” by the same writer, and is naturally drawn up on the same plan. Its size is handy, and yet it contains a very large amount of matter. Much of this ...

Mastering degree-radian conversions is crucial for trigonometry and calculus. Radians simplify mathematical formulas, especially in calculus where trigonometric function derivatives rely on radian ...

Trigonometric identities are powerful tools for simplifying complex equations in math and science. Three core groups—reciprocal, quotient, and Pythagorean—form the foundation. Effective strategies ...

In 2022, two high school students created a trigonometric proof of the Pythagorean Theorem—something that’s only ever been accomplished by a few professional mathematicians. Now, a new article not ...

NEW ORLEANS — The two women and St. Mary’s Academy graduates who used trigonometry to prove the 2000-year-old Pythagorean Theorem math equation, had their findings confirmed by the math experts after ...
