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 are the seven types of function?
There are infinitely many types of functions.
For example:
Discrete function,
Continuous functions,
Differentiable functions,
Monotonic functions,
Odd functions,
Even functions,
Invertible functions.
Another way of classifying them gives:
Logarithmic functions,
Inverse functions,
Algebraic functions,
Trigonometric functions,
Exponential functions,
Hyperbolic functions.
Does the tangent ratio ever get bigger than one?
Yes, it does. For an angle greater than 45 degrees (and less than 90), TAN will be more than 1. TAN of 50 is about 1.19.
What is the usage of trigonometry in mechanical engineering?
The usage of trig. in Mechanical Engineering is extensive. Trig. is used in almost every branch of the subject, especially where quantitative answers are needed to real physical problems such as the size of stresses in structural parts or the volume and frequency of a vibration.
What is the importance of trigonometry in physics?
The easiest way is physics, as does most of the real world, deals with vectors.
You are use to saying: 1 + 1 = 2 and the product of 2 and 3 is 6.
But what is 1 North + 2 South? It's 1 South. While that's an easy one, not everything lines up on an easy axis.
Vectors, unlike scalars, have both a magnitude and a direction. Often times you have to do operations to them, which you need a fundamental understanding of trigonometryfor.
Were did the word pistol come from?
From French, where it meant 'a whistle' - which is roughly the same shape. The word came into French from German and German took it from Czech.
How can you used trigonometry when you build skateboard?
the angle of the trucks could be determined using trig but it would depend if you had reverse kingpin or standard kingpin
Why use pie in periodic functions?
Pie is tasty.
Pi, however, is what you use in periodic functions.
+++
And you do so because periodic functions have properties linked to those of the circle. (You can illustrate this by plotting a sine curve on graph-paper, from a circle whose diameter is the peak-peak amplitude of the wave..)
Using the sine rule the possibilities are: 25 degrees, 28.93 degrees, 126.07 degrees with a 3rd side of 58.15 cm or 25 degrees, 151.07 degrees, 3.93 degrees with a 3rd side of 4.93 cm
How do you identify the domain and range?
Domain is a set in which the given function is valid and range is the set of all the values the function takes
What is the proof that sine 60 is square root of 3 divided by 2?
You could try the fact that the altitude of an equilateral traingle is also its median so that it divides the base in half. Then Pythagoras does the rest.
How the distance between two cities was measured and is measured now?
The distance between the countries can be find by travelling
What is an example of an angle bisector?
in a pie chart (divided into 4 for the sake of easiness ) the 360o circle is bisected into 4 90o angles
196-164/2= 16
Trigonometry is the study of triangles and their properties
10 feet, and it is at a very dangerous angle.
How can you calculate the density and volume of earth give the formula?
Density = mass / volume
since earth is nearly spherical, Volume = (4/3)pi x r3
find volume, then divide this into the mass.
Which part of the angle is the vertex?
It is the angle opposite the given side of a figure (<CAB has Vertex of A because it is the tip of the moutain, which is the highest point)
