sin(190)cos(70)-cos(190)sin(70)

sin (19 0^{\circ}) cos (7 0^{\circ}) - cos (19 0^{\circ}) sin (7 0^{\circ})

\frac{3}{2}

Solution steps

sin (19 0^{\circ}) cos (7 0^{\circ}) - cos (19 0^{\circ}) sin (7 0^{\circ})

Rewrite using trig identities:

sin (12 0^{\circ})

= sin (12 0^{\circ})

Use the following trivial identity:

sin (12 0^{\circ}) = \frac{3}{2}

= \frac{3}{2}

arctan (1.04)

arcsin (\frac{1.2}{1.6})

arctan (1.15)

cos (2) (π)

\frac{5}{cos ( 6 0 ^{\circ} )}
