Is there anywhere on the web I can find a chart of the exact values (in fractions, square roots) for sin, cos, tan, sec, csc, cot values...?

all in degrees...

cot (-150)

sec (-330)

csc (-210)

sec (-450)

csc (-675)

sec (315)

sin (-120)

cos (-90)

tan (-135)

cot 930

sin 630

My teacher gave us the unit circle chart and a chart of the basic values for sin, cos, tan, csc, sec, cot for 0, 30, 45, 60, and 90 degrees (for example, cos of 30 degrees = sq rt (3)/2 ). I just don't know what to do with them to solve for the other problems.
