Answer 1

$x \: e(0. \frac{\pi}{2} )$

$\cos(x) = \frac{3}{5}$

$sin(2 \times 0)$

$rezulta$

$\sin(0) = 0$

$\cos(2 \times 0)$

$rezulta$

$cos(0) = 1$

$\pi = 3.14$

$\cos(0) = \frac{3}{5} \: rezulta \: 1 = \frac{3}{5} rezulta \: 1 = 0.6 \: fals$

$\cos( \frac{3.14}{2} ) = \frac{3}{5} \: rezulta \: cos(1.57) = 0.6 \: fals$
