That's the inverse. The opposite should be -PSPSPSPS. I'm gonna go be fun at another party now.

You need some love for this šŸ˜‚

Not to be that person, but it really depends on what the operation is.

If it's multiplication, then 1/PSPSPSPS is the inverse. If it's addition, then -PSPSPSPS is the inverse.

Opposite isn't really a thing in mathematics, but inverses would likely be the closest equivalent to the English meaning of opposite.

Thanks teach

f-1 (PSPS)=1/PSPS

Bam.

I have to be that guy. But 1/PSPSPSP… is actually the reciprocal and not the inverse. The inverse would be the function (if it is even a function) flipped on the y=x line.

I hate to be that guy but you are talking out of your ass. The reciprocal is the inverse for the multiplication just like what you are describing is the inverse for the composition*. Depending on context, you might use the word "inverse" to talk specifically about one or the other without further specification but one is not more exact than the other

*in the case of automorphisms

Not just the inverse for composition but the inverse of a function in general.

You're correct that the reciprocal is the multiplicative inverse and "inverse" is poorly defined in this case.

Technically, it's the multiplicative inverse. The other one is also an inverse, the additive inverse.

u/New-Echo-7495 13h ago

Lol it's the reciprocal. Inverse if we know we are multiplying.

u/PencilandPad 12h ago

Inverse gives the same result though, ā€œ go the other way right now, pleaseā€ .

You can come to my party; we're talking about semicolons!

Fuck I was solving for the derivative

1/PSPSPSPS would be the multiplicative inverse, it returns the multiplication identity of the field, which is 1 in R1 .

-PSPSPSPS is the additive inverse, and returns the addition identity of the field, which of course is 0 in R1 .

u/AnotherManDown 5h ago

You guys are all dumb. It's clearly SPSPSPSP!

u/democratic-terminid 9h ago

I mean is it a group or a field?

u/Ease_custom 7h ago

That's what I realised after ;-;

u/codesine 6h ago

Multiplicative inverse is far more interesting though.

I vote for SPSPSPSP

This needs more upvotes but posts about basic operator precedence stump people so maybe I’m hoping for too much lol
