Trigonometry

The solutions do depend on what the questions are!

It is a trigonometric function. It is also continuous.

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.

because one side is concave and the other is convex

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.
