Trigonometry

A triangular-based pyramid is called a Tetrahedron. :)

A trapezium is a shape with four sides. Of these, one pair of sides are parallel. The only restriction on the other pair is that they are not parallel (because you then have a parallelogram).

WHAT ARE THE TANGENTS OF ALL COORDINATES IN THE UNIT CIRCLE?

Trigonometry (from Greek trigōnon "triangle" + metron "measure") is a branch of mathematics that studies triangles, particularly right triangles. Trigonometry deals with relationships between the sides and the angles of triangles, and with trigonometric functions, which describe those relationships and angles in general, and the motion of waves such as sound and light waves.

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. The sine and cosine functions are fundamental to the theory of periodic functions such as those that describe sound and light waves.

Fields that use trigonometry or trigonometric functions include astronomy (especially for locating apparent positions of celestial objects, in which spherical trigonometry is essential) and hence navigation (on the oceans, in aircraft, and in space), music theory, acoustics, optics, analysis of financial markets, electronics, probability theory, statistics, biology, medical imaging (CAT scans and ultrasound), pharmacy, chemistry, number theory (and hence cryptology), seismology, meteorology, oceanography, many physical sciences, land surveying and geodesy, architecture, phonetics, economics, electrical engineering, mechanical engineering, civil engineering, computer graphics, cartography, crystallography and game development.

Architect, they need to know trigonometry functions, among others they utilize to find the size of unknowns parts of shapes.

Surveyors, carpenters.

Trig is not restricted to angles, it has huge applications in waves, and occurs frequently as solutions to certain common differential equations. It is needed by any job that uses math. Thus, all engineers need trig, and it would be beneficial to any person who pursues science.

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. The answer may be "polygon" but it is difficult to tell when the question is unclear.

Radius is calculated by dividing diameter by two.

Measure the distance across the circle then divide it in half for example:

You measure the distance across the circle (the diameter) = 6,

then 6 divided in half, the radius is 3.

Deka is a prefix meaning ten times.

current ratio = current assets / current liablities A ratio (in trig) is simply the division of two lengths. A tangent (in trig) is the ratio of the opposite and adjacent legs.

A cube has six faces. Here is some more information about cubes.

A cube is a 3-dimensional polyhedron with 6 square faces.

Each vertex, or pointer corner, is occurs where three sides meet.

A cube has 12 edges and 8 vertices.

Another name for a cube is a regular hexahedron.

A cube is one of 5 platonic solids.

i want an example of geometric linear equations

A function f(x) is even if f(-x) = f(x). A graph of f(x) would be symmetric about the y-axis (vertical symmetry about x=0). f(x) need not be "well-behaved" or even continuous, unlike the examples given in Wikipedia article on "Even and odd functions". The article does make this clear - under "Some facts".

It is 3/13 - 2/13*i

3cot(A) = 4

so cot(A) = 4/3

then tan(A) = 1/(4/3) = 3/4

and so 1 - tan(A) = 1-3/4 = 1/4

It is 0.

logx = 0.25 =1/4 4logx = 1 log x^4 = 1 x^4 = 10 x = 4th root of 10 =1.778

The cosine is ±1/sqrt(5) = ±0.4472 (approx).

It is 10/18 = 0.55... radians.

Presumably this is a quadratic equation question in the form of 35x2+34x+8 = 0 35x2+34x+8 = 0 (7x+4)(5x+2) = 0 Answer: x = -7/4 or x = -2/5 Usually you can factorise a quadratic equation by trial and improvement but in this case it's quicker to use the quadratic equation formula.

For many people, math is not a subject that comes naturally, and trigionometry is no exception, especially because many fail to see the real-world application.

1/sin x = csc x

Let's call the unknown length x and use Pythagoras' theorem: x2+(x+3)2 = (x+6)2 By substituting 9 for x you'll find that only 9 will satisfy the above conditions. Shorter side = 9 units Longer side = 12 units Hypotenuse = 15 units
