30 degrees
explanation
2Cosx-radical 3=0
Then 2cosx=radical 3
and cos x=(radical 3)/2
Now remember that cos 300 is (radical 3)/2 from the 30/60/90 triangle.
So the answer is 30 degrees.
0.70710678118654752440084436210485 ----------------------- Improve: If you mean 45 degrees then it equals: Sqrt (2) /2 (which is the exact form of the above approximate form)
The exact value of 60 degrees would be 1/2. This is a math problem.
The exact value is 0.5*sqrt(3)
2.61
tan(-60 degrees) = - sqrt(3)
Exact value means you do not approximate. So if you answer has a radical in it, you leave the radical and do not approximate it. If it has a fraction such as 1/3, you leave it and do not approximate it as .3 or .33 or even.333333333333333...

The radical answer is sqrt(3)/2. (0.86602540378443864676372317075294)
you tell me
360 degrees equals 2(pi) radians. Therefore, [2(pi)](623/360) = (623/180)(pi). Since I have not discovered any common integral factor for 623 and 180, I believe this is the simplest manner in which the exact radians measure can be written.
The radical answer is sqrt(3)/2. (0.86602540378443864676372317075294)
well there's three answers to this question one of them is one and the other two are roots of a quadratic equation that include the imaginary number i. forgot the exact answers but i remember that you have to factor x^3-1
The exact location of Egypt is 25 degrees north latitude and 30 degrees east longitude
The exact value of 60 degrees would be 1/2. This is a math problem.
Use Guassian quadrature with n=1 and n=2 and compare to exact value I=
The approx. latitude is 43 degrees north, and the approx. longitude is 88 degrees west. The exact latitude is 43.04 degrees north, and the exact longitude is 87.95 degrees west.
( 36 degrees north and 138 degrees east
