Application of Trigonometric Ratios:
1 answer:
9514 1404 393
Explanation:
Graphs of sine and cosine functions are readily available in your text, on the web, and in your graphing calculator or spreadsheet. A graph is also attached here.
The sine and cosine graphs are identical, except that the cosine function is shifted left 1/4 cycle relative to the sine function. Both parent functions have a peak value of 1, and a period of 2π. The sine function is symmetrical about the origin (an odd function), and the cosine function is symmetrical about the y-axis (an even function).

Given:
Consider the below figure attached with this question.
To find:
The perimeter of the polygon UVWXYZ.
Solution:
All sides and vertical and horizontal. So, we can easily find the side lengths of the given polygon by counting the boxes between two points.
From the figure it is clear that,
UV = 9 units
VW = 2 units
WX = 3 units
XY = 3 units
YZ = 6 units
ZU = 5 units
Now, perimeter is the sum of all the sides.
Therefore, the perimeter of UVWXYZ is 28 units.
