Question
Without using trigonometric tables, evaluate.
$\frac{\sin 28^{\circ} 54^{\prime}}{\sec 61^{\circ} 6^{\prime}}+\frac{\cos 28^{\circ} 54^{\prime}}{\operatorname{cosec} 61^{\circ} 6^{\prime}}$
$\frac{\sin 28^{\circ} 54^{\prime}}{\sec 61^{\circ} 6^{\prime}}+\frac{\cos 28^{\circ} 54^{\prime}}{\operatorname{cosec} 61^{\circ} 6^{\prime}}$
