Express each of the following in terms of trigonometric ratios of angles between \( 0^{\circ} \) and \( 45^{\circ} \).
(i) \( \sin 72^{\circ}+\operatorname{cosec} 72^{\circ} \)
(ii) \( \operatorname{cosec} 66^{\circ}+\tan 66^{\circ} \)
(iii) \( \tan 68^{\circ}+\sec 68^{\circ} \)
(iv) \( \cot 59^{\circ}+\operatorname{cosec} 59^{\circ} \)
(v) \( \cos 51^{\circ}+\cot 49^{\circ}-\sec 47^{\circ} \)
(vi) \( \sin 67^{\circ}+\cos 75^{\circ} \)
