Answer 1

1.

$a) \sin( \frac{3\pi}{2} ) = - \frac{1}{5} = > - 1 = - \frac{1}{5} = > - 1 = - 0.2 \: fals pt.ca \: t \: nu \: indemplineste \: conditia \: de \: mai \: sus$

$\sin(2\pi) = - \frac{1}{5} = > 0 = - \frac{1}{5 } fals \: pt.ca \: t \: nu \: indeplineste \: conditile \: impuse \: mai \: sus$

$b) \cos( \frac{\pi}{2} ) = - \frac{1}{4} = > 0 = - \frac{1}{4} fals \: pt. \: t \: nu \: indeplineste \: conditia \: de \: mai \: sus$

$b) \cos(\pi) = - \frac{1}{4} = > - 1 = - \frac{1}{4} = > - 1 = - 0.25 \: fals$
