tan^2(210)+sqrt(3)cos(330)

tan^{2} (21 0^{\circ}) + 3 cos (33 0^{\circ})

\frac{11}{6}

Solution steps

tan^{2} (21 0^{\circ}) + 3 cos (33 0^{\circ})

Rewrite using trig identities:

tan (21 0^{\circ}) = \frac{3}{3}

Rewrite using trig identities:

cos (33 0^{\circ}) = \frac{3}{2}

= (\frac{3}{3})^{2} + 3 \frac{3}{2}

Simplify

(\frac{3}{3})^{2} + 3 \frac{3}{2} : \frac{11}{6}

= \frac{11}{6}

4 tan (0.9) - \frac{4 ( 0.9 ) ^{3}}{3}

1 - cosh (0)

cos (114 0^{\circ})

cos (\frac{π}{2}) cos (\frac{π}{3}) + sin (\frac{π}{2}) sin (\frac{π}{3})

200 sin (2 0^{\circ})
