Question

Cколько будет 2arctg4/5

Answer 1

2 × atg(4 / 5) = 77,3196165082

Answer 2

Answer:

The expression 2arctg(4/5) can be calculated using the arctan function, which is the inverse of the tangent function. The arctan function returns the angle whose tangent is a given number. In this case, we want to find the angle whose tangent is 4/5.

Using the arctan function, we can calculate 2arctg(4/5) as follows:

2arctg(4/5)

First, find the arctan of 4/5: arctan(4/5) ≈ 38.66 degrees

Then, multiply the result by 2: 2 * 38.66 ≈ 77.32 degrees

So, 2arctg(4/5) is approximately 77.32 degrees.
