(-sin(pi/2))/(-cos(pi/2))

\frac{- sin ( \frac{π}{2} )}{- cos ( \frac{π}{2} )}

Undefined

Solution steps

\frac{- sin ( \frac{π}{2} )}{- cos ( \frac{π}{2} )}

Use the following trivial identity:

sin (\frac{π}{2}) = 1

Use the following trivial identity:

cos (\frac{π}{2}) = 0

= \frac{- 1}{- 0}

= Undefined

arctan (\frac{7}{- 4})

10 \cdot sin (7 0^{\circ})

sin (2) (π)

\frac{4}{sin ( 6 0 ^{\circ} )}

70 sin (4 0^{\circ})
