Rotate with Mindsensors AbsoluteIMU

It is necessary to know how to get the gyro rate from AbsoluteIMU

Blocked, it is necessary to know how to get the Rate of a Gyro

[jabrena]

Reading the documentation exist a way to get the angle:

There is a Trigonometric relation between the tilt readings and tilt angle of the sensor. As follows:
angle = sin-1 (tilt reading/128)
where tilt-reading is from Accelerometer at Sensitivity 2G.
also as a alternative to sin-1, you can use: angle = 2 * arctan(t / (1 + sqrt(1-t^2))),
where t ≡ tilt_reading / 128 to avoid a negative sqrt() operand when tilt_reading = 128.

2 * arctan(t / (1 + sqrt(1- (t^2))))
2 * atan (a / (1 + sqrt(1- (a^2))))

The calculus is for angle, but I don´t know how get Gyro Rate

I will continue the development using compass features
