When was trigonometry invented?
lol smiley face :-):D:
Total Cow DUMP!
It was invented in a town called New Hartley in 1390 Athens Greece.
Usage of trigonometry in mechanical engineering?
Trig is used in inspection. This is the department where every component made will be checked to make sure that it has been made to a satisfactory standard. Trig simply calculates all angles when taking other diemsions, so anles can be worked out.
You want a working model of mathematics for school exhibition what you should make?
area and perimeter of different shapes
43.3
What is the definition of plane trigonometry?
Plane trigonometry is trigonometry carried out in (on) a plane. This could be contrasted with spherical trigonometry, which is trigonometry carried out on the surface of a sphere. Certainly there are some other more complex forms of trig.
What is the formula for finding slope of a line using the coordinates of two points on a line?
you do y2-y1 over x2-x1
Square root of 2 Times Square root of 2?
The square root of two times the square root of two equals two
Why do you use greek symbols in trigonometry?
because the greek started trig 2000 years ago to work out where they were using the stars
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
A prayer with mathematical terms?
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
How do you work out the trigonometry of a rectangular based pyramid?
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.
What is the reciprocal of the tangent?
The reciprocal of the tangent is the cotangent, or cot. We might write 1/tan = cot.
Calculate 45 degree offset when the travel is known?
A 45 degree offset has a travel of 200mm. calculate the rise of the offset.
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.
Can you delete your wild tangent orb account?
No. You can contact the wild tangent support team to either block or disable it.
Angel's are very important in Islam as, they have a height status than any other of Allah's creation. angels are made out of light and they do not need food drink nor do they get tiered as they do not desire anything. the are continuesly wprshipping Allah's commands. Angels carry out various tasks, each angel has different tasks there for thwey have different powers.
it is iportant to believe in angels as Muslims are taught this in the quran and sunah, when a Muslim believe in Allah it fardz to believe in his angels as it is one of the pirncipal beiliefe in Islam.

The answer, although interesting, is about angels, not angles which is what the question was about!
Geometry has its roots in ancient people trying to measure plots of land which were flooded annually by the Nile. When the flood waters receded, land had to be restored to its former owners and it was important to know how much land each landowner had before the flooding. The likelihood that taxes were partly based on the area of land owned made it particularly important to get the calculations right. The areas of some shapes are relatively simple to calculate from the lengths of their sides but for some shapes it is easier if angles (and their trigonometric ratios) can be used in the calculations.
Sine, Cosine, Tangent, Cotangent, secant and cosecant
