AI Thread Summary
The letter "m" is conventionally used to represent slope in equations, primarily due to its placement in the alphabet, distinguishing it from variables like x, y, and z. There is no definitive reason for this choice, but it aligns with the practice of using letters from the beginning of the alphabet for parameters. Some participants expressed a preference for using "S" instead of "m" for slope. The discussion includes references to resources that explore the derivation of "m" in slope equations. Overall, the choice of "m" remains a matter of convention rather than a rule.

Why is the letter m used to represent slope?

I would rather S for slope.

There's not really any reason, it's just that letters towards the end of the alphabet (x, y, z, w, etc) are usually used for variables while letters away from the end are usually used for parameters.
 

Thread 'Trigonometry problem of interest'

Seemingly by some mathematical coincidence, a hexagon of sides 2,2,7,7, 11, and 11 can be inscribed in a circle of radius 7. The other day I saw a math problem on line, which they said came from a Polish Olympiad, where you compute the length x of the 3rd side which is the same as the radius, so that the sides of length 2,x, and 11 are inscribed on the arc of a semi-circle. The law of cosines applied twice gives the answer for x of exactly 7, but the arithmetic is so complex that the...

Thread 'Imaginary Pythagoras'

I posted this in the Lame Math thread, but it's got me thinking. Is there any validity to this? Or is it really just a mathematical trick? Naively, I see that i2 + plus 12 does equal zero2. But does this have a meaning? I know one can treat the imaginary number line as just another axis like the reals, but does that mean this does represent a triangle in the complex plane with a hypotenuse of length zero? Ibix offered a rendering of the diagram using what I assume is matrix* notation...

Thread 'Fermat's Last Theorem'

Fermat's Last Theorem has long been one of the most famous mathematical problems, and is now one of the most famous theorems. It simply states that the equation $$ a^n+b^n=c^n $$ has no solutions with positive integers if ##n>2.## It was named after Pierre de Fermat (1607-1665). The problem itself stems from the book Arithmetica by Diophantus of Alexandria. It gained popularity because Fermat noted in his copy "Cubum autem in duos cubos, aut quadratoquadratum in duos quadratoquadratos, et...
