Сравни числа:

1. \(\sin 40\degree\) и \(\sin 160\degree\) ;

2. \(\cos 70\degree\) и \(\cos 280\degree\) .

Ответ:

1. [ \(\sin 40\degree\gt\sin 160\degree\) | \(\sin 40\degree\lt\sin 160\degree\) | \(\sin 40\degree=\sin 160\degree\) ];

2. [ \(\cos 70\degree\gt\cos 280\degree\) | \(\cos 70\degree\lt\cos 280\degree\) | \(\cos 70\degree=\cos 280\degree\) ].
