1. The minute hand of a clock moves from 12 to 4 o’clock or 1/3 of a complete revolution. Through how many degrees does it move?  Through how many radians does it move?

2. A lawn sprinkler rotates through an angle of 1350 and projects water over a distance of 40ft.  What is the area of the lawn watered by the sprinkler?  Express your answer in terms of π and then round to two decimal places.

3. q is an acute angle and sin q ans cos q are given.  Use identities to find tan q , csc q , sec  q, and cot q .  Where necessary rationalize denominators.

sec  q = 3/5       and    cos q = 4/5 

4. Find the exact value of the expression below.  Write the answer as a single fraction.  Do not use a calculator. 

Sin π/ 4 cos0 – sin π/6 cos π
