74.08
Step-by-step explanation:
Remember that cos(0) represents the x value of a point on the unit circle. The period for the unit circle is 2π in radians which means that adding or subtracting 2π will get you back to the same point which has the same cosine.
Examples: cos(2π),cos(100π),cos(60π)
Answer:
{a universal set is a set which contains all objects, including itself}
Step-by-step explanation:
a) you will create two circle, crossing over each other, and shade both the "A" the "B" and the middle space.
b) (AUB) means the same thing as universal set, but its called union, infact if you draw this out in Venn Diagrams this will be the exact same as answer (a).
c) A n B : mean A 'intersection' with B, so here you will only shade the area where both circles meet.
d) i am not sure of this one, sorry
