Trigonometry

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.

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

He defined the spherical triangle

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.

It is 0.

The angular velocity of a pulley turning 1800 rpm is 60 pi radians per second.

It's roughly one half of the acceleration of gravity on earth.

You can either go to a tanning bed, get a spray tan, or lay out in sun and tan. All except for spray tans can lead to severely increased chances of skin cancer, however.

sin(26 deg) = 0.4384, approx.

trigonometric tables can be be used for this purpose. but to calculate the values without any external help, one can use the traditional method of derivation using different geometrical figures. for example the value of sine 600 can be calculated using an equilateral triangle. the ratio of altitude to half the length of side is (sq.root of 3)/2. but that is also sine600. but that is a tedious method of calculation. it is much easier to remember the rational or irrational values of standard angles like 300 450 600 750 900. the values of few other angles can be calculated from these using trigonometric identities and other formulae.

Engineers use trigonometry anywhere that involves non-right angles. That includes building cars and buildings, bridges, and many other structures. they also use trigonometry when dealing with fields, like magnetic and electric fields. Also, trigonometry is very important with engineers who deal with waves, such as sound or light engineers.

They could help construct buildings is the only one i could think of

They are the coordinates.

Suppose you are given the three sides of a triangle and the altitude from the apex to the base. The altitude divides the triangle into two right-angled triangles and the arcsine function can be used to determine the two base angles. Subtracting their sum from 180 gives the third angle.

There are 20 unique 5-card hands.

Solution:

First break apart the player card combinations.

You can either use player card 1, player card 2, or both player cards 1 and 2 with the hand. Therefore, you are taking 5 cards, 3 at a time, when playing with both player cards, and 5 cards, 4 at a time, when playing with 1 player card.

Mathematically, this can be expressed using the Binomial coefficient

2 x ( 5 choose 4 ) + ( 5 choose 3 ) = Number of possible 5-card hands.

5 choose 4 = 5 : This represents the combinations between 1 player card and 5 table cards, 4 at a time. (http://www.wolframalpha.com/input/?i=5+choose+4)

5 choose 3 = 10 : This represents the combinations between 2 player cards, and 5 table cards, 3 at a time. (http://www.wolframalpha.com/input/?i=5+choose+3)

Thus, 2 x ( 5 ) + ( 10 ) = 20 .

Further Information:

All possible hand combinations are listed below.

A and B are the two player cards.

0 through 5 are the five table cards.
