Trigonometry
Trigonometry is a field of mathematics. It is the study of triangles. Trigonometry includes planar trigonometry, spherical trigonometry, finding unknown values in triangles, trigonometric functions, and trigonometric function graphs.

What is cosine used for outside of math class?
Surveyors, physicists, astronomers, construction people, chemists and other professions would use the trig functions outside of class. Burger flippers? Not so much.
How do you apply trigonometry in other fields?
There are an enormous number of uses of trigonometry and trigonometric functions. For instance, the technique of triangulation is used in astronomy to measure the distance to nearby stars, in geography to measure distances between landmarks, and in satellite navigation systems.
Wikipedia has a page on the uses of trigonometry. Click on 'related links' below to go to that page.
What is the functions and what is relation in trigonometry?
The same as in any other math class. All functions are relations but all relations are not functions. A function must have only one 'answer' in the range for each value of the domain. Relations are just pairing of numbers with no such restriction on the range.
How many questions do i have to get right out of 160 to get a 300 scoring to pass?
That is a good question because the NCBTMB keeps many of its inner workings a mystery. First of all, they only count 120 out of the 160. Also, they do not use a straight percentage, they use a scaled score; they adjust the percentage in relation to the different versions of the test.
A rough guess, since only they know which questions count, would be about 120 right answers to pass the 600 question exam.
Definition of equivalent sets?
two sets A and B are said to be equivalent if there exists a bijective mapping between A and B
4x to the 4 power and y to the 7 power divided by 8x to the 5 power and y to the 3 power?
(4x4 + y7)/(8x5 + y3) cannot be simplified.
What is the importance of trigonometry?
Spherical trigonometry is important because the Earth is a sphere, not a plane, so if you wanted to get the distance between one point on Earth and another, plane trigonometry wouldn't give you the right answer. Plane trigonometry can be used to find the height of something without having to climb it, such as a flagpole or skyscraper. Trigonometry, whether spherical or planar, is used in engineering to design buildings, cars, ships, and planes. It is used in physics to calculate the properties of electric and magnetic fields. It is used in navigation, and projectile motion. It is also used in the design of musical chords and instruments, as well as lenses and optics.
Does the graph of cotangent have any asymptotes?
Yes, at k*pi radians (k*180 degrees) where k is any integer.
Using trigonometry the angle of elevation is 77 degrees rounded to the nearest degree
A tangent is a line segment, line, or ray that intersects a circle or curve at only one point.
Additionally, a tangent is the ratio in any right triangle of the length of the opposite side to the length of the adjacent side. It will be a constant for every right triangle of any size with the same interior angles.
first of all,INTERSECTION means cutting,second;tangents do not occur always in ONE POINT.They might being involved in more than one .
To understand and visualize an approach to a tangential condition there are two numerical functions bringing it fort;
a-[(n+1):(n)]^(n)
b-[(n+1):(n)]^(n+1)
one tends to approach the Limit upward and the other downward,but there is always a tendency to become in contact.
In a right triangle, the tangent of one of the acute angles is the side opposite the angle to the side adjacent to it.
In terms of sin and cosine it's the ratio of sin to cosine (or sin / cosine).
How much does one centilitre equal to one mililitre?
1 centiliter = 10 milliliters
centiliter: a metric unit of volume equal to one hundredth of a liter (10−2 L)
milliliter:a metric unit of volume equal to one thousandth of
liter (10−3 L)
How is law of sines used trigonometry?
The 3 little division "sums" that are the Sine and its brother ratios, Cosine and Tangent, given in any basic right-angled triangle, form the basis for the entire, vast field of Trigonometry and its uses, going far beyond simple Plane Geometry into such things as Harmonic Analysis (Sine functions of amplitude with respect to time), the Laws of Electricity (starting with the phase angle between Volts and Current in a.c. circuits, etc.), and so on.
The cosine of 2pi is 1. In fact, for every integer N, the cosine of 2 N pi is 1.

What is the domain and range of a quadratic function?
The domain and range can be the whole of the real numbers, or some subsets of these sets.
How do you find quadratic equation with only 2 solutions?
If the discriminant of the quadratic equation is equal or greater than zero it will have 2 solutions if it is less than zero then there are no solutions.

What sort of triangle has 3 equal sides and 3 equal angels?
the only triangle that has 3 equal sides and 3 equal angles is the EQUILATERAL TRIANGLE.
What is a good grade in trigonometry?
It is all about personal preferrence and what type of college you plan to attend. As long as you work hard, and give it your all, you should get a good grade. Colleges will look at your overall GPA, but if you truly a major course such as trigonometry, your chances may be hurt.
-------------------------------------------
It depends on the course and what your definition of "good" is. For a typical school course in the United States, strive for a 90% (A) or better.
How do you convert a sine curve function to a cosine curve function?
One way is to shift it to the left by a quarter of the period.
