Trigonometry

A polygon with eight sides and eight angles.

The square root of two times the square root of two equals two

because the greek started trig 2000 years ago to work out where they were using the stars

The reciprocal of the tangent is the cotangent, or cot. We might write 1/tan = cot.

The answer depends on what you wish to work out: the angles, height, surface area, volume. Also, you need more information: the vertical or inclined height and whether or not the pyramid is a right pyramid.

A 45 degree offset has a travel of 200mm. calculate the rise of the offset.

Delta, is just a Greek letter very used in Math. It's meaning depends on the context.

But a very common meaning, specially for capital delta ( a triangle) is difference. For instance, a temperature Delta usually means the difference of the temperatures of 2 objects. In your case, it probably means the difference of the given values

lord sorry for all of our sin,

forgive us lord to make it correct

Lord teach us to number our days

And graph them according to your ways

Trusting you to base me in our plan

To complement your perfect diagram

Subtract the points you do not want from us

But add the values you have set for us

Divide the dividends we possess accordingly

So I can multiply them systematically.

Draw the lines we have to follow

Guide us properly with your arrow

Because sometimes we tend to be irrational

Yet all the while you want for us is to be rational.

Well we learn that life is like a slope

With its ascends and descends that I must cope

Going through such a wonderful formula

Give thanks and praise your Almighty creation

The volume is 14,137.2 cm3

tan A = (sin A) / (cos A)

tan (A)= opposite side length/adjacent side length

A is an angle measurement; amount of degrees or radians.

If a line is tangent to a curve, it only touches the curve at one point. looks like )| but the line is touching the curve.

In a circle, the tangent line touches the circle at one point and is perpinducular to the circle's radius if it is touching that same point.

Various trigonometric functions, such as sine or cosine, show the relationship between the lengths of sides of a triangle and the angles between those sides. So trigonometry is used to calculate angles, lengths and distances using right triangles. Right triangles are those that have one angle of exactly 90 degrees.

Example: You want to find the height of a tree. Measure off a fixed distance from the tree and measure the angle between the ground and the line-of-sight to the top of the tree. The height of the tree = the distance to the tree times the tangent of the angle between the tree and the ground, ie tan(x).

The answer is rather complicated but I will do my best. Let's consider logs in base 2 as those are the easiest. We can make a table quite easily:

log2_1 = 0

log2_2 = 1

log2_4 = 2

log2_8 = 3, etc.

Notice that in order to get a whole number answer we had go by powers of 2. So we know the logarithms for 2, 4, 8 etc. But what if we want to find the logarithm of say 3? Now I don't quite remember where I saw this but to find a logarithm between two others we take:

logB_square root[X * Y] and [C + D] / 2 with the logs being logB_X = C & logB_Y = D with the log being between them. For example take:

log2_2 = 1 and log2_8 = 3 using the formula we get log2_sqrt[2 * 8] = [1 + 3] / 2 =

log2_4 = 2 which you can clearly see is between the two logs. Now to find log2 = 3 we take:

log2_2 = 1

log2_4 = 2

sqrt of 2 * 4 = 2.828 approximately and [1 + 2] / 2 = 0.5 so we get:

log2_2.828 = 0.5; to get closer that 3 is between log2_2.828 and log2_4 so using the formula on them we have: sqrt [2.828 * 4] and [0.5 + 2] = 1.25

log2_3.63 = 1.25; then continuing a few times:

log2_3.20 = 0.875; used log2_3.63 and log2_2.828

log2_3.00 = 0.6875; used log2_3.20 and log2_2.828

We can keep going getting closer and closer to 3. We got 3.00 because I was rounding the answers on the calculator. We can actually go on forever always getting closer. We stop when we notice we start getting the same answer. Notice that each time we used the formula we kept the log we wanted in between the 2 logs we used. This is IMPORTANT! If the log you want isn't in between the logs you use for the formula you will not get the right answer. Now this nowhere near precise but I hope you get the idea. To get more accuracy you should keep more decimal places. Like if you want 5 decimal places keep 6 and then when you're done round your answer. Also note that there is formula to change the base. It is:

[logB_C] / [logB_D] = logD_C

So once you make a table of logarithms in one base you can use the formula to conver them to any base you wish. I can always help clarify if anyone has trouble getting this.

None.

A trapezium is a rectangle with its top line shorter then the bottom one.

Jonathan Sisson invented the theodolite, which measures both horizontal and vertical angles, in 1720, according to the Alberta Land Surveyor's Association. This instrument resembles a mounted telescope, and a user can adjust the height of the platform so his eyes are level with the ocular lens.

Find the area of a triangular section, 1/2bh, and then multiply by the length of the prism.

Just like most any other set of functions, trigonometric functions are subject to differentiation. Trig functions are cool (at least sin and cos are) because as you differentiate, they cycle through until you get back where you started.

Just Look Around Or If Worse comes to worse buy a trig text book

thanks you for your help

find the volume & total surface of a square pyramid, the side of the base being 4meters & height 5meters

360 / 4 = 90 It is 90 degrees

You need to specify what quantity you're trying to find.
