Missing "+1" in final solution by chrys

Type: Erratum
Correction text:
Currently the second line reads,
sqrt( 1 + (2x)^2 + (6y)^2 ) = sqrt( 4x^2 + 36y^2 )
I believe the RHS, or solution, is missing the "+1". The correct equation should read:
sqrt( 1 + (2x)^2 + (6y)^2 ) = sqrt( 1 + 4x^2 + 36y^2 )
This carries over to Example 8 as well. |
Comment from object owner yark:
Thanks - looks like I didn't even read the entry when I adopted it!
> This carries over to Example 8 as well.
Please file a separate correction for that one, as I'm not the owner. |
