Question

Can anyone help me with this?

Determine the angle between the following vectors in R4:
(i) v1 = (1, 0, 2, 2) and v2 = (4, 2, 1, 2);

Answer 1

are you asking me

Answer 2

no but i can try use what i have in vector analysis

Answer 3

If two vectors u and v have an angle θ between them, then\[\cos \theta =\frac{ u∙v }{ \left| u \right|\left| v \right| }\]

Answer 4

@Sportaholic013 understand?
