Using the above method we got an acceleration value of (x and y and z).Now i want to find angle between (x and y) and (y and z) and (z and x).How can i do this?

Can anyone help me ?

Thanks in advance…..

    If your acceleration vector is a = (x, y, z), then the angles between this vector and the three axes are given by:

    cos (angleXaxis) = x / sqrt(x^2 + y^2 + z^2)

    cos (angleYaxis) = y / sqrt(x^2 + y^2 + z^2)

    cos (angleZaxis) = z / sqrt(x^2 + y^2 + z^2)

    To get the angles themselves you’ll need to use the inverse cos function
