Did you think about using vectors ?
Alright people im struggling with this vector question;
Deduce the triangle inequality,
||a-c|| <= ||a-b|| + ||b-c||
Ive been stuck on this question for ages now, and ive tried various attempts to solving it.
Can any one help me out? Cheers
David.
No, I meant using vector properties (they go quite well with triangles) and look if you can't work out your equality from this. By the way, is your triangle scalene or is it some particular type of triangle ? And what do you mean by ||a-c|| ? Does it mean the length of the vector , which is ?
