# Vectors abs sum diff

The vectors a = (4,2), b = (- 2,1) are given.
Calculate: a) |a+b|, b) |a|+|b|, c) |a-b|, d) |a|-|b|.

Correct result:

a1 =  3.6056
a2 =  6.7082
a3 =  6.0828
a4 =  2.2361

#### Solution:

${a}_{4}={a}_{0}-{b}_{0}=4.4721-2.2361=\sqrt{5}=2.2361$ We would be pleased if you find an error in the word problem, spelling mistakes, or inaccuracies and send it to us. Thank you! Tips to related online calculators
