Trigonometry

Trigonometry helps surveyors determine sides of a triangle which are either inaccessible or difficult to access. Knowing the length of a single base line enables the surveyor to define the other elements of the triangle by measuring the angle to the inaccessible points from accessible points.

Consequently the heights of trees and tall buildings can be determined by knowing the distance to the base of the tree or building. Similarly locations separated by, for example, rivers or busy roads can be determined by angular measurement from positions of known distance apart on the other side of the obstruction.

Survey control marks used for the mapping of countries were in the past established by triangulation from a known base line.

These days much of the survey control is undertaken using GPS equipment which uses satellite signals to determine positions on earth. However the theory behind the location of these positions also uses trigonometry and spherical trigonometry.

The definition of a true compass bearing - A true bearing is measured in relation to the fixed horizontal reference plane of True North, that is using the direction towards the geographic North Pole as a reference point.

A scalar times a vector is a vector.

No, it does not.

If tan A = 1/2, then sin A = ?

We use the Pythagorean identity 1 + cot2 A = csc2 A to find csc A, and then the reciprocal identity sin A = 1/csc A to find sin A.

tan A = 1/2 (since tan A is positive, A is in the first or the third quadrant)

cot A = 1/tan A = 1/(1/2) = 2

1 + cot2 A = csc2 A

1 + (2)2 = csc2 A

5 = csc2 A

√5 = csc A (when A is in the first quadrant)

1/√5 = sin A

√5/5 = sin A

If A is in the third quadrant, then sin A = -√5/5.

Amongst the lay public of non-mathematicians and non-scientists, trigonometry is known chiefly for its application to measurement problems, yet is also often used in ways that are far more subtle, such as its place in the theory of music; still other uses are more technical, such as in number theory. The mathematical topics of Fourier series and Fourier transformsrely heavily on knowledge of trigonometric functions and find application in a number of areas, including statistics.

Well, there really are no leaders in Twelve Angry Men, but those with more 'input' would include Juror #1 (Martin Balsam) the Foreman and Juror #8 (Henry Fonda) who pushes for fellow jury members to consider the possibility the Defendant may not be guilty of the crime.

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 geometric term for the number of square units needed to cover a surface is called the area of said surface.

A parabola is a single curve: it does not have separate parts.

The law of sines states the in a triangle with sides of length a, b, and c, and angles of A, B, and C where each angle's letter corresponds with the side opposite it, that Sin(A)/a = Sin(B)/b = Sin(C)/c. The law of cosines states that for the same triangle, c2 = a2 + b2 -2abCos(C).

A plane is a flat surface with no thickness. Our world has three dimensions, but there are only two dimensions on a plane.

Here are three:

If you have the area - radius = sqrt( A/Pi )

If you have the diameter - radius = D/2

If you have the circumference - radius = (C/(2Pi))

3060 degrees is eight and a half revolutions.

So the sine of 3060 degrees is the same as the sine of 180 degrees (half a revolution)

sin 180 = 0

A rectangular pyramid is a solid (3-dimensional) figure that comes to a point opposite the base (like the Pyramids of Egypt.) Its base is a four-sided plane figure with right angles and opposite sides equal (a rectangle--or square for that matter).

I like geometry. It gives me pleasure in my life. how about you.
