Question

Tentang trigonometri nih^^​

Answer 1

Jawaban:

(d) hanya (4) saja yang benar

Penjelasan dengan langkah-langkah:

[tex](1) \: cos \: p \: = \frac{x}{r} = \frac{ \sqrt{11} }{6} \\ (2) \: cos \: r \: = \frac{x }{r} = \frac{5}{6} \\ (3) \: {(tan \: p)}^{2} = {( \frac{y}{x} })^{2} = { (\frac{5}{ \sqrt{11} } })^{2} = \frac{25}{11} \\ (4) \: sin \: r \: = \frac{y}{r} = \frac{ \sqrt{11} }{6} = \frac{1}{6} \sqrt{11} [/tex]
