Q2:
Which one of the following would be equivalent to sin(30)? Why?

A
cos(60); the sine and cosine will be the same because the angles are complementary
B
cos(60); the sine and cosine will be the same because the angles are supplementary
C
sin(60); the sines of the two angles will be the same because the angles are complementary
D
sin(60); the sines of the two angles will be the same because the angles are supplementary

a function could be identified in 3 ways either on a chart,graph, or ordered pairs. first a function is that each point has its own. the rule is that there can be many x's to one y but there can not be 2 x's at different y's. so on a graph when you put a straight line through the y's there should be one dot only to be a function.
