- Homework Statement
- Because v<<c in this case, we can expand the denominator

(1 + x)^-1 = 1 - x + ... keeping only the lowest term in x

v/c. The above equation becomes...

I am wondering if there is a typo in my textbook. Please see the attachment. The textbook says "...keeping only the lowest term in x = v/c." I am wondering if it should be "x = v/(nc)," as I circled in blue on the left side. It is a binomial expansion of the denominator. Shouldn't x be v/(nc) instead of v/c? The textbook says "...keeping only the lowest term in x = v/c." Thank you.
