What does this symbol mean?

[lwon Dis2I]

What does this symbol mean? I have not found anywhere in the book where it defines it.

[Faith Veenker 2K]

From what I remember from the lectures, I believe it means "proportional to."

[Elizabeth Kaplan 3I]

This symbol means "proportional to", and is useful when you are describing the relationship between two variables. For example, if one variable is "proportional to" 1/another variable, they have an inverse relationship, and if one variable is "proportional to" another variable, they have a direct relationship.

[Moura Girgis 1F]

That symbol stands for "proportional to" and is used to describe how one thing is the same as or equal to another thing. Similarly, it can be used to describe something as "inversely proportional" to another thing when that second term has a "^-1" on it.

I'm glad someone asked this because I was wondering too! This is the first time I've seen professors use this notation so thank you for the clarification!

[Katelyn_Ortega_1D]

I was really confused on what that meant too so thank you to the people who clarified, it really helped.

[Diana Aguilar 3H]

I was also very confused on what this symbol meant, so thank you to everyone who clarified what it was!

[Rayna Irving 2C]

Thanks for asking this, I saw it too and I wasn't sure exactly what it meant so these answers are very helpful!

[Michelle Nguyen 3F]

It means "proportional to" ! In some of the example equations in the textbook, the sign shows up often. Hope this helps. :)

[Katelyn_Ortega_1D]

When I saw that symbol for the first time, I was also very confused. Thank you to everyone who helped clarify!

[Emma_Barrall_3J]

Proportional to. Meaning following the same trend.

[Aria Movassaghi 1A]

That symbol is called alpha and it means "proportional to"

[Lindsey Walter 3E]

This symbol means "proportional to"! Basically, it would mean that the variables would both increase and decrease at the same rate!

[Skylar Lo 2C]

The symbol shows proportionality and is used to describe relationships between different related values.

[Riya Sawhney 1C]

The kind of elongated/open alpha symbol indicates proportionality! For example, E∝v, and the proportionality constant is h (E=hv).

[Arden Napoli 1E]

That symbol indicates a "proportional to" statement.

[Vanessa Wiratmo 3k]

The symbol means "proportional to"
The symbol is known to the the Greek letter alpha. You use the symbol in between two variables/quantities. For example, if x and y had an alpha in between them, that that means x is directly proportional to y.

[Arjun_Anumula_3E]

That symbol is used to relate 2 values that are proportional to each other. For example, in Planck's equation E=hv, the energy of a photon is directly proportional to the photon's frequency

[noahbehrendt2L]

This symbol means "promotional to". It indicates a proportional relationship between variables, meaning they increase and decrease at the same rate.
