Matematika Minat kelas 10
penjelasan dan langkah langkah :
[tex]a = 2i \: + 4j \\q = 15i - 8j \\ \\ p \: q \: = (4) \: ( - 1) \: + (1) \: (4) \\ = - 4 \: \: \: \: + 4 \\ \\ p.q \: \: = 0 \\ \\ p = 4 \sqrt{ {4 }^{2} } + \sqrt{ {1 }^{2} } \\ \\ \\ = \ \\ [/tex]
[tex] = \sqrt{17 } \\ \\ q . \sqrt{( - 1 {)}^{2} } + {4}^{2} \\ \\ q. = \sqrt{17} \\ \\ cos \: \: p \: \: . \: q \\ \\ = \frac{0}{? \sqrt{17 \: \: . \sqrt{17} } } \\ \\ = [/tex]
[tex] = \: cos \: = 0[/tex]
