AI Thread Summary
The discussion centers around a controversial exam problem involving a zebra chased by a crocodile, which caused significant distress among students. Participants question the requirement to solve the problem without using calculus, arguing that students aged 17 and 18 are expected to understand differentiation, which is essential for finding maxima or minima. Many agree that differentiation is part of the math curriculum, making the no-calculus requirement puzzling. The thread concludes with the original poster closing the discussion to prevent further time-wasting. The debate highlights the disconnect between exam expectations and students' mathematical knowledge.

without Calculus...
Why without calculus? 17 and 18 year olds studying maths would generally be expected to at least know how to differentiate, and that the derivative will be zero at a maximum or minimum, which is all that's required here. Further, the comments below the article seem to agree that differentiation was part of the curriculum.

Thread 'What Exactly is Dirac’s Delta Function? - Insight'

Insights auto threads is broken atm, so I'm manually creating these for new Insight articles. In Dirac’s Principles of Quantum Mechanics published in 1930 he introduced a “convenient notation” he referred to as a “delta function” which he treated as a continuum analog to the discrete Kronecker delta. The Kronecker delta is simply the indexed components of the identity operator in matrix algebra Source: https://www.physicsforums.com/insights/what-exactly-is-diracs-delta-function/ by...

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...

Thread 'Imaginary Pythagorus'

Thread 'Imaginary Pythagorus'

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...
