I Equivalence Question between when-then statement and if then statement

AI Thread Summary
The discussion centers on the equivalence of "when-then" statements and "if-then" statements in logic. The original poster is confused about which proposition to assume for a proof involving "when p is true, then q is true." Participants clarify that "when" can often be interpreted similarly to "if," suggesting that the statement does not imply a temporal condition. Some also note that language differences, particularly in translation, may contribute to the confusion. Ultimately, the consensus is that "when" can be treated as "if" in logical contexts.

TL;DR Summary
What is the equivalence between when then and if-then statement
Dear Everybody,

I am working on my homework. I am trying to prove a problem that was written by my professor in an odd way: Prove that when p is true, then q is true. Which proposition statement should I assume? I personally thought that I should assume the first one. But reading my introduction to proof writing it says "Q, when P for implication statement." Now, I am confused on what to assume?

Thanks,
Cbarker1

Who wrote the book? I'm pretty sure we can assume "if" in those cases, except in case the statement is time-dependent.
 
I forgot to add that my professor wrote the problem.
 
I was asking because it might be a language issue. "If" in German is "wenn" so it could be a translation problem. Another, possibly more likely reason could be that "when" is commonly used in the same sense as "if", disregarding the timely connotation of "when". When it happens it does not necessarily require a time scale. It simply means if it happens.

I can't see that "when p is true, then q is true" could possibly mean "if q, then p". Words and phrases like "assuming", "whenever", "when", "in the event that", "under the assumption that" etc. are sometimes used instead of the more formal "if".
 
Suppose ,instead of the usual x,y coordinate system with an I basis vector along the x -axis and a corresponding j basis vector along the y-axis we instead have a different pair of basis vectors ,call them e and f along their respective axes. I have seen that this is an important subject in maths My question is what physical applications does such a model apply to? I am asking here because I have devoted quite a lot of time in the past to understanding convectors and the dual...
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...
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...
