Trigonometry

Technically they don't because the definition of a point is a specific place of a certain object in a graph, and you could keep cutting up the point infinity times and still not have the most exact location as possible. Thus, a point can be any shape, but for a point there will never be an exact location or a definite size or shape. Most points in geometry are little circles such as on a line graph, but a point could be a square. A point is just the most exact location of something in a geometry problem. That's all it is.

Ummm... there is this thing called practice ;)

Theta is the measure of the angle, whether in degrees or radians.

The purpose of trigonometry is to gather as much accurate measurements of distances given little information about angles or other distances. It is used in engineering, astronomy, city planning, drafting and designing, and construction.

That tool is called a protractor.

If you have a right triangle, the sine of an angle is the ratio of the opposite side to the hypotenuse.

There is none because it is not true.

Same as anywhere: opposite to a clock's conventional rotation. Mathematicians like to put x = 0º on the x-axis (so y = Sin x = 0) and measure anticlockwise from there.

Trigonometry is specificly the study of a right triangle. For example, what is the cosine? Geometry is the study on shapes.

The question, as it appears, does not make any sense. Please try to use a sentence when asking a question, if it is not too much effort.

Undefined!!!! Can't answer it! All sine and cosine values are between -1 and 1 !!!

sin(2*pi/65537) = 0.0001

cos(2*pi/65537) = 1.0000

Pythagoras. He has the Pythagorean Theorem named after him.

The differential of the sine function is the cosine function while the differential of the cosine function is the negative of the sine function.

volume = 1/2 x width x length x height

Basically it is working out the properties of triangles and angles of various polygons.

You could model the tides as a simple harmonic motion. This is a form of a sine (or cosine) curve and will enable you to predict the times when the tide is coming in, reaches high tide, when it is ebbing and low tide. This information should help determine the best surfing time.

Actually, I don't know how to make your feet smaller but all I do is wear black tennis shoes and bell bottom jeans. They work a lot!! Believe me! Cause where I live, a lot of guys are always telling me I have big feet. This is how I solve the problem. Oh! And converses always make your feet look bigger. Just a tip there.

The cosine of 8 degrees is 0.99026806874157031508377486734485
