sin(2arccos((sqrt(3))/2))

sin (2 arccos (\frac{3}{2}))

\frac{3}{2}

Solution steps

sin (2 arccos (\frac{3}{2}))

Rewrite using trig identities:

2 sin (arccos (\frac{3}{2})) cos (arccos (\frac{3}{2}))

= 2 sin (arccos (\frac{3}{2})) cos (arccos (\frac{3}{2}))

Rewrite using trig identities:

sin (arccos (\frac{3}{2})) = \frac{1}{2}

Rewrite using trig identities:

cos (arccos (\frac{3}{2})) = \frac{3}{2}

= 2 \cdot \frac{1}{2} \cdot \frac{3}{2}

Simplify

2 \cdot \frac{1}{2} \cdot \frac{3}{2} : \frac{3}{2}

= \frac{3}{2}

tan (0.7)

sin (arcsin (\frac{1}{6}))

10 cos (\frac{π}{6})

arccsc (\frac{3}{2})

10 cos (2 0^{\circ})
