====================================================
Explanations:
- a) y = sin(theta) describes the height of the point (x,y). Because m = sin(theta), this means m is the height.
- b) Cosine is not positive in quadrants II and III, where x < 0. This is because x = cos(theta).
- c) Adding pi radians to the angle theta will rotate it 180 degrees to have it land in the fourth quadrant (southeast quadrant).

Answer:
In terms of probablity (A - appetizer oredered, B - desert ordered)
P(A)=63%
P(B)=40%
P(AorB)=76%.
Using the formula:
P(AorB)=P(A)+P(B)-P(A&B) we get P(A&B)=63%+40%-76%=27% (probability we were looking for).

The idea is to use the tangent line to 
at 
in order to approximate 
.
We have
so the linear approximation to 
is
Hence 
and 
.
