    Trigonometry of effective wind from yaw angle (see link)

    hi, first post........Can anyone help me with the formula for "effective air velocity" assuming I have 1 yaw angle; 2 front/head air velocity and 3 side air velocity? There is a calculator here (apparent wind angles) but I cannot figure out the formula for "effective air velocity" from the other variables.

    thank you!
