Question

Heme Anslues is
2
( operatorname{amin}left[-1, frac{1}{sqrt{2}}right] frac{1}{cos a operatorname{tion}=frac{a operatorname{tis} f y}{downarrow}} )
take ( frac{sqrt{3}}{2} )
( cos ^{2} frac{sqrt{3}}{2}=30^{circ} quad ) cos ( quad sin ^{7} 1 / 2=30^{2} )
( sin ^{2} sqrt{3} / 2=60^{circ} )
then, 2 and 4 one wrong
