Trigonometry

One of them is the Hindu-Arabic numeral system which we use today and another is the Roman numeral system which was used by the ancient Romans

The period of 1 MHz is 1 microsecond.

The waveform is irrelevant.

The subject has not concluded: there are still aspects of it that can be developed so it is premature to talk about the conclusion of the subject.

A dilation would produce a similar figure.

The perimeter of a triangle, given only two sides and no information about angles, cannot be determined. However, it can be said (if the two given sides were A and B) that the perimeter cannot be less than 2A or 2B, whichever is more, nor more than 2(A+B).

These are limiting cases. In the first case, A or B approaches zero, which makes C approach B or A. In the second case, A and B have an angle approaching 180 degrees, making C approach A+B.

It is simple the study of triangles: the properties of their sides and angles. This is then extended to other, more complicated polygons and polyhedra, but the basis is still the triangle.

The answers depend on what you want to "do" and what information you have.

The grad is a unit of plane angle, equivalent to 1⁄400 of a fullcircle. It is also known as gon, grade, or gradian (not to be confused with thegrade of an inclined surface, i.e.gradient, slope, or pitch, the gradient in vector calculus, or the radian unit). One grad equals9⁄10 of a degreeorπ⁄200 of a radian. In continental Europe, the French term centigrade was in use for one hundredth of a grad, and the termmyriograde[citation needed]was in use for one ten-thousandth of a grad. This was one reason for the adoption of the term Celsiusto replaceCentigrade as the unit of temperature.

y = 1.5x+8

So the slope is 1.5 and the intercept is 8

The frequency of a sine wave can be thought of in several different ways:

-- watching the wave from one fixed point, the number of times the wave reaches its maximum amplitude

in one second, or the number of complete waves that pass you in one second

-- the speed of the wave, divided by the distance between two consecutive maximum points on it

-- the reciprocal of the time it takes for one complete wave to pass you (' 1 ' divided by that length of time)

Gymnastics came from the greek word "Gymnos" which means naked

It is (tanA+tanB)/{tanA*tanB} - 1/(tanA+tanB)

Because infinity is not a umber, it is usually not treated as a number when computing functions. Instead, you can look for a limit of a function as it approaches infinity. For example, the limit as x approaches infinity of 1/x is 0. Because sine oscillates, it's value constantly moves up and down, and it's value as it approaches infinity is not defined because it does not converge on any one number, as some other functions (like 1/x) do.

An inrease in the retirement age would effectively increase a country's labor supply, shifting the production possibilities curve right.

Geometry is the study of all shapes. This includes octagons. Trigonometry developed much later than geometry for applying the study of triangles to practical application.

You cannot.

Geometry (Greek γεωμετρία; geo = gaia or earth, metria = measure) is a part of mathematics concerned with questions of size, shape, and relative position of figures and with properties of space. Geometry is one of the oldest sciences. Initially a body of practical knowledge concerning lengths, areas, and volumes, in the third century B.C., geometry was put into an axiomatic form by Euclid, whose treatment - Euclidean geometry - set a standard for many centuries to follow. The field of astronomy, especially mapping the positions of the stars and planets on the celestial sphere, served as an important source of geometric problems during the next one and a half millennia. However, the real problem with geometry is that these shapes we speak about are not, in reality "geo" or of earth, but rather in our minds as mental gymnastics. That is why calculus was developed in an attempt to measure the curvatures that elude geometric forms' more linear factors. Essentially, the circle is considered classically as a geometric form and perhaps should be. But the problem remains that albeit a circle would be more relevant to physical life as of it curvature, the problem remains of its measured exactitude. Since we have pi radius squared as the area of circle, we find that "pi" is a fraction and therefore, not exact. Classical math tries to dodge this question regarding the inexactness of a circle claiming equations exist to measure it exactly, but even the Fibonacci sequence is a fraction at 1.625 (some argue 1.618, but do the math of the square root of 5 minus 1 divided by 2). Therefore, the exacting factor means nothing and we must move on from there. It is similar to Einstein's claim to fame because his deflection of light theory was .83 of second arch more than Newton's at .87 second. Who cares about these exiguous degrees when 2/3 of the world is starving? We spend 200 million dollars on the restoration of the Parthenon in the past thirty years equating an obvious misprioritization when our neighbors starve to death. How sad.
