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
The radical answer is sqrt(3)/2. (0.86602540378443864676372317075294)
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.
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=
( 36 degrees north and 138 degrees east
Less than 90 degrees.
