Below is an instruction that describes a task. Write a response that appropriately completes the request.

### Instruction:
If the coordinate velocity v dx/dt in units of c is (e 2 − 1)/(e 2 + 1) ≅ 0.761, what is the velocity angle η in i-radians?

### Inputs:
table_name: table, columns: ['Condition/Parameter', 'Coordinate velocity v dx/dt in units of c', 'Velocity angle η in i-radians', 'Proper velocity w dx/dτ in units of c', 'Lorentz factor γ dt/dτ = E/mc 2']

### Response:
SELECT Velocity angle η in i-radians FROM table WHERE Coordinate velocity v dx/dt in units of c = (e 2 − 1)/(e 2 + 1) ≅ 0.761
