Answer:
- complex plane; (cos(θ)+i·sin(θ))^n = cos(nθ) +i·sin(nθ)
- relationship between parameter and coordinates
- basically: (x, y) = (r·cos(θ), r·sin(θ)); can be solved for r, θ
Step-by-step explanation:
1. de Moivre's theorem (or identity) states that ...
It is a statement about powers of complex numbers, so is related to the complex plane.
__
2. To graph a parametric equation, you need to know the relationship between the parameter and the coordinates you want to graph.
__
3. Here are the relationships:
(x, y) = (r·cos(θ), r·sin(θ))
(r, θ) = (√(x² +y²), arctan(y/x)) . . . with attention to quadrant

Irrational numbers are the subset of real numbers that are not at all connected to the rest of numbers.
The subsets of real numbers are natural numbers, whole numbers, integers, rational numbers and irrational numbers.
Natural numbers are subset of whole numbers, which are subset of integers, which are subset of rational numbers. Hence, all of them are interconnected. The set of irrational numbers is the only subset of real numbers which is not associated with the rest.
For example:-
1 is a natural number, whole number, integer, rational number but not irrational number. On the other hand, is an irrational number but none of the rest.

Step-by-step explanation:
y-intercept is defined as the point where the graph crosses the y-axis. The value of x coordinate at this point is zero, as along entire y-axis, the value of x coordinate is always zero. So substituting x = 0 in the function will give us the y-coordinate of the y-intercept of the given function.
Substituting x = 0 in this function, we get:
Thus, the y-coordinate of the y-intercept is 1. Therefore the y-intercept of the function in ordered pair will be: (0, 1)
