Trigonometry

well theprobability would be 2x52/4 which is about 26%

cos2A = cos^2A-sin^2A (2A means the double angle .. :|)

when we taking the right angle triangle,in this when taking the 30 degrees of one side ,then the ratio of the opposite side to the hypotenuse will 0.5 always.and this is called sin30 in trigonometry and...............this is answered by sreenivassn from narayana engineering college,gudur.

This is NOT a Pythagorean triangle.

So we must fall back on the Cosine Rule for an agular value.

Cosine Rule is a^(2) = b^(2) + c^(2) - 2bcCosA

Algebraically rearranging

CosA = [a^(2) - b^(2) - c^(2)] / -2bc

Substituting

CosA = [10^(2) - 7^(2) - 5^)2)] / -(2(7)(5))

CosA = [100 - 49 - 25]/-70

CosA = 26/-70

CosA = -0.371428571...

A = Cos^(-1) -0.371428573

A =111.8037 481 ... degrees. -

Now area of triangle is 0.5 X Base X height

The height is = 7Sin(111.8037481...)

Hence are is 0.5(5)(7)Sin(111.8037481...)

Area = 16.248... m^(2)

The Arc of a circle is that part of the circumference between two radii.

Sin(theta) = 0.03125

Hence

theta = ArcSin(0.03125)

theta = 1.790784659... degrees.

There is no other names!!!!

Howver 'the word' trigonmetry' comes from Latin, and means 'measuring triangles.'.

trigon ( a three sided 2-dimenstional figure) = triangle (modern).

Metry = to measure.

if tan x = cos x then

sin x / cos x = cos x

=> sin x = cos x cos x

=> sin x = cos2 x

=> sin x = 1 - sin2x

=> sin2x + sin x - 1 = 0

Using the quadratic formula

=> 1. sin x = 0.61803398874989484820458683436564

=> x = sin-1 (0.61803398874989484820458683436564)

or

=> 2. sin x = -1.6180339887498948482045868343656

=> x = sin-1 (-1.6180339887498948482045868343656)

4 sin(theta) = 2 => sin(theta) = 2/4 = 0.5.

Therefore theta = 30 + k*360 degrees or 150 + k*360 degrees where k is any integer.

All six trigonometric functions can take the value 1.

This depends on whether 23 is in radians or degrees. If it is in degrees, then the answer is approximately 0.92. If it is in radians, then the answer is approximately -0.53.

The value of cos 46 degrees is approximately 0.7193. Cosine is a trigonometric function that represents the ratio of the adjacent side to the hypotenuse in a right triangle. In this case, when the angle is 46 degrees, the cosine value is calculated by dividing the length of the adjacent side by the length of the hypotenuse.

the answer is 2500

I am sorry but this answer is wrong. You only added the numbers between 1 and 100. The question is the first 100 odd numbers, you need to add 1 to 197. The correct answer is 10,000.

You can calculate this on any scientific calculator. Those calculators don't usually have a special key for the cosecans, but this is the same as 1 / sin(63).

Well, honey, to round 10.9 to 1 decimal place, you just look at the digit right after the decimal point. If it's 5 or greater, you round up. So, 10.9 rounded to 1 decimal place is 11. Easy peasy, lemon squeezy!

Do you mean (((216^(1/2))^(1/2))^(1/2)) or [216^(1/2)] / 3

The first answer is 216^(1/8) = 1.957973....

The second one is 216^(1/2) / 3 = 4.898979486....

Oh honey, without the Order of Operations, you're just asking for a hot mess. Trying to solve complex math problems without following the correct order of operations is like trying to bake a cake without a recipe - you're gonna end up with a disaster. So, technically speaking, any math problem becomes a nightmare without those rules in place.

The cotangent function is the reciprocal of the tangent function, so cot(115 degrees) is equivalent to 1/tan(115 degrees). Since tan(115 degrees) is equivalent to -tan(65 degrees) due to the periodicity of the tangent function, cot(115 degrees) simplifies to -tan(65 degrees), which corresponds to option A.

Sin30 degrees is 0.50000

The circumference of a 12-inch round circle in pi is: 12pi

is called the 'origin' , and has the co-ordinates of (0,0)

Well, using a^2 + b^2 = c^2, where a and b are the legs and c is the hypotenuse, you need to square 39 and 36. Then your equation should look like a^2 +1296 = 1521, then solve for a^2, getting the variable by itself, so you have a^2 = 225. Then take the square root of both sides leaving you with a= 15. So, the ladder must be placed 15 feet from the base of the house.

tan a=1/2 tan b=1/3 find tan (a-b)

Well, darling, to find the area of a triangle with those side lengths, you can use Heron's formula. So, plug in those side lengths (a=8, b=11, c=15) into the formula, calculate the semi-perimeter, and then solve for the area. Voilà, you've got yourself the triangle's area.

Tangent of theta = Y/X, or opposite the angle/the adjacent of angle. So;

Tangent of 42 degrees = height/80'

80' tan 42 = height

= 72 feet ( you might want to subtract that 4.5 foot eye height )
