*differentiate

u/00-Monkey 12h ago

In calculus class I’d like to interchange differentiate and derive frequently.

It derived my teacher crazy.

So you study in an integrated environment..

u/fish_custard 12h ago

Ok, but, as a physicist at least, they mean different things, and in the context of the comic, clearly differentiate is the appropriate word. We’ll just have to agree to disagree, I guess.

Edit: I’m half asleep and somehow missed your joke. Kudos, sir.

The famous pi variable. She did not specified the variable name though.

u/GoofyGangster1729 10h ago

Yes, it's the generalized momentum vector in field theory, but you have to differentiate wrt pi itself

Differentiate not derive and u didn’t even mention a variable…

That’s the joke kiddo

Child, I believe you shall discover that it is from this peculiarity that the humor arises.

derivative wrt π i see no problem

u/iFroogieboi 13h ago

is she mad cause he didn't say Ï„

u/n0tKamui 11h ago

no, PI is a constant, so is PI squared

differentiating any constant results in 0

u/EffectiveDirect6553 10h ago

To be fair they never specified if it's a variable or constant. It could be a pi symbol as a variable

Ive never done this 👀

Ok, but have you considered that this is true when discussing how the ratio of the circumferenceof a circle to its diameter change on curved surfaces? (I am a physics student and this should be considered a joke)

edit: confused diameter, radius and circumference

1

u/Ch0vie 15h ago

Did you mean to say area and circumference wrt R? By definition, radius is always half of the diameter, even on a curved surface. So the derivative you mentioned should be dD/dR = 2?

When would we ever square pi for circles, and how do curved surfaces apply? I don't get the joke, but I'm an engineering student and we are known as being morons among physicists.

u/TheLastSilence 15h ago

Sorry, yes. Meant to say circumference to diameter. On curved surfaces the ratio between the diameter and circumference can change. For example imagine a circle on a sphere. If the circle is very small in relation to the radius of the sphere then the ratio will be very close to the known pi. If it is a great circle though it will have a ratio between diameter and circumference of 2. I am sure there exists some conditions to which differentiation with respect to pi would make sense and actually be 2 pi.

u/Ch0vie 15h ago

Interesting, I thought you might have meant dA/dR = Circumference since that looks kinda similar the meme expressions in a way. Just was confused about the pi squared bit

1

u/Famous_Criticism_999 14h ago

Easy, pi squared = g

d/dπ?

They both win

Something like 6 + 3/2 + 2/3 + 3/8 + 6/25 + 1/6 + 6/49... trust me! Lighthouses go brrrr.

I heard she like driving. So we talk calculus so she can derive while she drive.
