arcsin(cos((43pi)/5))

arcsin (cos (\frac{43 π}{5}))

- \frac{π}{10}

Solution steps

arcsin (cos (\frac{43 π}{5}))

Rewrite using trig identities:

cos (\frac{43 π}{5}) = sin (- \frac{81 π}{10})

= arcsin (sin (- \frac{81 π}{10}))

Use the inverse trig property:

- \frac{π}{10}

= - \frac{π}{10}

2 cos (\frac{π}{6}) + sin (\frac{5 π}{6}) - tan (\frac{π}{3})

e^{s i n (0)} cos^{2} (0) - e^{s i n (0)} sin (0)

- 2 (- 2 sech^{2} (0) tanh^{2} (0) + sech^{4} (0))

arctan (0.67)

\frac{sin ^{3} ( \frac{π}{2} )}{3}
