Question

Арккотангенс(1/2) ( arcctg) =?

Answer 1

Arcctg(1/2)=x
ctgx=1/2
arcctg(1/2)€(0;π)

Answer 2

To find the arccotangent of 1/2, we can use the relationship between the arctangent and arccotangent functions.

The arccotangent function (arcctg or arccot) is the inverse of the cotangent function (cot). In other words, if cot(x) = y, then arcctg(y) = x.

We know that the cotangent of an angle is equal to the reciprocal of the tangent of that angle. Therefore, if cot(x) = 1/2, then tan(x) = 2.

To find the arctangent of 2, we can use a calculator or reference table.

Using a calculator, we find that the arctangent of 2 is approximately 63.43 degrees or approximately 1.107 radians.

Therefore, arcctg(1/2) is equal to approximately 63.43 degrees or approximately 1.107 radians.
