• How can I PROVE that ||u-v|| is less than or equal to ||u|| + ||v||?

  I am not asking why, I understand why. I have to write a proof and I haven't figured it out. I know that the triangle inequality states that ||u+v|| is less than or equal to ||u|| + ||v||. I have tried using schwartz inequality, starting with ||u-v||^2 = (u - v) dotproduct (u - v) and do some manipulations but haven't gotten anywhere. I tried to prove that ||u-v|| is less than or equal to ||u+v|| but that isn't always true. I can't just state something like the sum of two sides of a triangle are always larger than the third side. I need to write a proof and I am stuck. Anyone good at linear algebra?
