Can you help me find the values of sin,cos & tan of and to find exact values of:

Think about a 906030 right triangle for the first problem.
What is the side measurement opposite of the angle pi/6(30 degrees)?
For second problem, it is in the fourth quadrant. Draw a right triangle in the fourth quadrant and you will see the answer.
Same for number three but its in the third quadrant.
