Jika Vektor vektor dan . Vektor satuan dari vektor adalah ...

Jika Vektor begin mathsize 14px style a with rightwards arrow on top equals open parentheses table row 2 row 3 end table close parentheses end style vektor begin mathsize 14px style b with rightwards arrow on top equals open parentheses table row 3 row 9 end table close parentheses end style  dan begin mathsize 14px style c with rightwards arrow on top equals a with rightwards arrow on top plus c with rightwards arrow on top end style. Vektor satuan dari vektor begin mathsize 14px style c with rightwards arrow on top end style adalah ...

Jawaban:

begin mathsize 14px style c with rightwards arrow on top equals a with rightwards arrow on top plus b with rightwards arrow on top space space space equals open parentheses table row 2 row 3 end table close parentheses plus open parentheses table row 3 row 9 end table close parentheses space space space equals open parentheses table row 5 row 12 end table close parentheses end style 

Vektor satuan dari begin mathsize 14px style c with rightwards arrow on top end style 

begin mathsize 14px style table attributes columnalign right center left columnspacing 0px end attributes row cell fraction numerator c with rightwards arrow on top over denominator vertical line c with rightwards arrow on top vertical line end fraction end cell equals cell fraction numerator 1 over denominator square root of 5 squared plus 12 squared end root end fraction open parentheses 5 comma 12 close parentheses end cell row cell space space space space space space space space end cell equals cell fraction numerator 1 over denominator square root of 25 plus 144 end root end fraction open parentheses 5 comma 12 close parentheses end cell row cell space space space space space space space space end cell equals cell 1 over 13 open parentheses 5 comma 12 close parentheses end cell row cell space space space space space space space space end cell equals cell open parentheses 5 over 13.12 over 13 close parentheses end cell row blank blank cell space space space space space space space end cell end table end style  

Jadi, vektor satuan dari begin mathsize 14px style c with rightwards arrow on top end style adalah begin mathsize 14px style open parentheses 5 over 13 comma 12 over 13 close parentheses end style
