Trigonometry

A hexagon is a six-sided figure. Cut an equilateral triangle out of a piece of paper. Chop off little equilateral triangles at each tip of the triangle. What you have is a hexagonal piece of paper. Draw around it.

They are measures of angular displacement. In two dimensional space they may be measured in degrees (by beginners) or in radians. There are 2*pi radians in a revolution.

In 3-d space angles are measured in steradians. A sphere measures 4*pi steradians

The period of 1GHz is 1 ns.

The waveform is irrelevant.

Usually applied to accounting, so I will answer based on accounting. If a company has 3000 accounts numbered from 1 to 3000. Lets say you are to look at 100 files. 3000/100 = 30, random sampling is not choosing every 30th account. That does not give an equal chance of selecting each file. File 101 would never be selected. This is a biased sampling. You must use some kind of random number generator to select the 100 files to look at so that every file has an equal probability of being reviewed.

The main part of trigonometry is the study of triangles on spheres. Also, another part of trigonometry is the constant positive curvature.

1.An ant is determined to climb a flagpole that is 18 feet tall . Each day

2.a sphere has two sides . However there are one sided surfaces.

By Pythagoras, if the initial height of the ladder is H1 feet, then

252 = H12 + 92 so H12 = 252 - 92 = 544 so that H1 = 23.32 ft.

After the move, the base of the ladder is 15 ft from the wall. If the height now is H2 feet, then

252 = H22 + 152 so H22 = 252 - 152 = 400 so that H2 = 20 ft.

So the ladder will slide down 3.32 ft or 3 ft 3.9 inches, approx.

Placing a question mark at the end of a phrase does not make it a sensible question. Try to use a whole sentence to describe what it is that you want answered.

an equilateral triangle

sec(x) = 2

so cos(x) = 1/2

and so x = pi/3

An octahedron is an eight sided polyhedron. It has eight sides or faces, 12 edges, and six vertexes. Please see the Related Link below for more information and a picture.

(a+b)/a=a/b=phi (the golden ratio, as defined)

(a+b)/a=phi (we'll solve this equation)

1+b/a=phi (just changing the form of the left side a little)

1+1/phi=phi (a/b=phi so b/a=1/phi)

phi+1=phi2 (multiply both sides by phi)

phi2-phi-1=0 (rearrange)

From here, we can use the quadratic equation to find the positive solution:

phi=(-b+√(b2-4ac))/(2a)

phi=(1+√(1+4))/2

phi=(1+√5)/2≈1.618

trigon = triangle

metry = measurement.

To calculate the cosine in a right angled triangle:

Length of adjacent side divided by the hypotenuse.

Every angle has a vertex. A vertex is simply the line through the center of each angle. The line splits the angle exactly in half.

Mathematics are important to pilots in many many many ways. Every pilot is aware of the effect weight and balance has on aircraft performance and must be able to use simple equations to quantify these effects on paper before applying them on the runway. Likewise, geometry is vital when navigating aircraft. There are no highways to speak of, and so aircraft navigate using directional headings. Pilots must also be able to use the navigation radio system to triangulate their location on charts and the like.

Pilots are constantly figuring numbers in their heads. Whether he's calculating the ETA based on airspeed minus windspeed (corrected for wind direction) divided by the remaining distance to destination or using fuel consumption info to figure out if that headwind is going to keep him from making it in one go, a good pilot is always thinking of some number it seems. Computerized systems have made some of this automatic, but there will always be a need for math in the cockpit.

Length of hypotenuse using Pythagoras' theorem: 2.86 cm rounded

Smallest using cosine rule: 35.02 degrees rounded

For disabled access, regulation elevation is between 1:12 and 1:20

Consider the mapping between two sets, A and B. To each element of A is associated a unique element from the set B.

The elements of set A which are mapped (the inputs) comprise the domain. The corresponding elements from set B comprise the range.

We can use trigonometry in construction in several aspects:

1- Measure field, lots and areas; -- surveying uses trigonometry extensively

2- Make parallels or perpendiculars walls;

3- Install ceramic tiles;

4- Define roof inclination;

5- calculate how long to make diagonal support beams

And many others...

Construction workers

can use trigonometry it to find the distance of a wall of diagonal space in a rectangle shaped room.

Also, you should go ask your math teacher about this for further information.

angle can be defined as sin-1=O/H, cos-1=/H, or Tan-1=O/A

The word 'Viking' is an Old Norse word for a week-long sea voyage. It is cognate with the English word 'week'.
