Has anyone seen this formula before?Has anyone seen this formula before? Or one very similar? "When subtracted from 180, the sum of the squareroot of the two equal angles of an isocoles triangle squared will give the squareroot of the remaining angle squared." #2 20050801 20:15:20
Re: Has anyone seen this formula before?Zmurf, Character is who you are when no one is looking. #3 20050801 20:32:36
Re: Has anyone seen this formula before?Oh ok. But what formula would I use if i want to find the angle oposite to side 'b' if i'm only given the lengths of sides 'a' and 'b' and the angle between them? "When subtracted from 180, the sum of the squareroot of the two equal angles of an isocoles triangle squared will give the squareroot of the remaining angle squared." #4 20050801 20:42:14
Re: Has anyone seen this formula before?Can I have a go at simplifying? "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #5 20050801 20:54:47
Re: Has anyone seen this formula before?Here: A Why did the vector cross the road? It wanted to be normal. #6 20050801 20:59:05
Re: Has anyone seen this formula before?
With the help of the formula Character is who you are when no one is looking. #8 20050802 00:44:30
Re: Has anyone seen this formula before?Sometimes, I really, really want to be older. School is practice for the future. Practice makes perfect. But  nobody's perfect, so why practice? #9 20050802 07:37:03
Re: Has anyone seen this formula before?
How did you get to the c²  2bc (cos θ) + b² (cos θ)² ? "When subtracted from 180, the sum of the squareroot of the two equal angles of an isocoles triangle squared will give the squareroot of the remaining angle squared." #10 20050802 07:48:30
Re: Has anyone seen this formula before?Well, just by expanding. "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #11 20050802 07:57:35
Re: Has anyone seen this formula before?
You are just on the edge of learning this, I think. For the moment don't be "overawed" by it. In a few years you will say "ah, obviously!" "The physicists defer only to mathematicians, and the mathematicians defer only to God ..."  Leon M. Lederman #12 20050802 14:21:31
Re: Has anyone seen this formula before?
You can expand the terms as Mathsisfun said. Character is who you are when no one is looking.
