(sin(45))/(sin(30))

\frac{sin ( 4 5 ^{\circ} )}{sin ( 3 0 ^{\circ} )}

2

Solution steps

\frac{sin ( 4 5 ^{\circ} )}{sin ( 3 0 ^{\circ} )}

Use the following trivial identity:

sin (4 5^{\circ}) = \frac{2}{2}

Use the following trivial identity:

sin (3 0^{\circ}) = \frac{1}{2}

= \frac{\frac{2}{2}}{\frac{1}{2}}

Simplify

\frac{\frac{2}{2}}{\frac{1}{2}} : 2

= 2

arcsin (1.7)

cos (3 0^{\circ}) \cdot 100

8 sin (5 0^{\circ})

cos (arctan (\frac{11}{60}))

500 sin (2 0^{\circ})
