# Thread: Defining the terms of an equation

1. ## Defining the terms of an equation

Dear teachers,

Is this the best way to describe the terms of an equation?

Professsor Einstein showed that energy is proportional to mass with this equation:

E = m*c^2

where(in):
E=energy;
m=mass;
c=speed of light
;

It seems to me that 'wherein' fits better considering the nature of the context.

Thank you 2. ## Re: Defining the terms of an equation

As an NES but not a teacher, I would normally use "where" in such cases, but "wherein" or "in which" would probably also work for me.

"Wherein" is the type of word found in legal documents and not in common use. 4. ## Re: Defining the terms of an equation Originally Posted by SoothingDave "Wherein" is the type of word found in legal documents and not in common use.
Oops! True. I've been writing too many legal documents. Regards

I'd use "where" too.

Where x equals 10 and b equals 4, you'll find that x and y together give you 14.

There you go, equations for beginners. To clarify, I got the lowest pass mark possible in my only maths exam, at the age of 16. #### Posting Permissions
