What is the formula for calculating the angle between two vectors ?⃗? and ?????
?⃗? ∙ ???? = |?⃗? | |????| cos (?⃗? , ???? )
a) ?⃗? ∙ ???? = |?⃗? | |????| sin (?⃗? , ???? )
b) ?⃗? ∙ ???? = |?⃗? | + |????| cos (?⃗? , ???? )
c) ?⃗? ∙ ???? = |?⃗? | - |????| cos (?⃗? , ???? )
d) ?⃗? ∙ ???? = |?⃗? | |????| tan (?⃗? , ???? )
?⃗? ∙ ???? = |?⃗? | |????| cos (?⃗? , ???? )
a) ?⃗? ∙ ???? = |?⃗? | |????| sin (?⃗? , ???? )
b) ?⃗? ∙ ???? = |?⃗? | + |????| cos (?⃗? , ???? )
c) ?⃗? ∙ ???? = |?⃗? | - |????| cos (?⃗? , ???? )
d) ?⃗? ∙ ???? = |?⃗? | |????| tan (?⃗? , ???? )
