Here are the solutions to the questions:

1. evaluate cos 60 / sin 30

Step 1: Recall the standard trigonometric values for $\cos 60^\circ$ and $\sin 30^\circ$ .

\cos 60^\circ = \frac{1}{2}

\sin 30^\circ = \frac{1}{2}

Step 2: Substitute these values into the expression.

\frac{\cos 60^\circ}{\sin 30^\circ} = \frac{\frac{1}{2}}{\frac{1}{2}}

Step 3: Simplify the expression.
