Hello!</h2>
The asnwer is: Cos50° ≈ 0.643
<h2>
Why?</h2>
A unit circle is a cirgle with a radius equal of 1, knowing that, also know the following:
The angle is drawn passing trough the unit circle at (0.643,0.766) it means that:
So,
Cos50° ≈ 0.643
We can prove that by following the next steps:
- If it's a unit circle,here is a right triangle with hypotenuse of 1,
- We can determine the cosine of the angle by the following formula:
Therefore,
Cos(α)=49.98°≈50°
Also, if there is a right triangle, according to the Pythagorean Thorem:
Hence,
Cos50° ≈ 0.643
Have a nice day!
Vectors give us direction and distance. the first part of our ordered pair moves us in the x direction (left and right), and the second member of the ordered pair moves us in the y direction (up and down)
if you plotted each point along the move, you would go from (7,17) and move -1 in the x direction and 0 in the y, ending up at (6,17). From there, we move 2 in the x direction and 7 in the y, to (8,24).
basically we just add all of the x's together and the y's together since we are moving in a specific direction from a point to a new point.
so
x=7+-1+2+2=10
y=17+0+7+10=34
and we end up at (10,34)
In the video about the construction of the insect phylogeny, the researchers faced the problem that there was not enough computational power in all of the world to construct every possible tree.
The use of computing algorithms, tools, and programmes to phylogenetic analysis is known as computational phylogenetics. The purpose is to create a phylogenetic tree that represents a hypothesis about a set of genes, species, or other taxa's evolutionary ancestry.
There was not enough computational power to construct every possible tree in all of the world. So the probable solution for this problem will be:
Use math to avoid constructing improbable trees
