    Calculate Tangent in VB.NET ***RESOLVED***

    I am trying to figure out the azymuth betwen two points using the following

    azymuth = 90 - (tanE-1(DeltaN/DeltaE)

    i have been given the answer of 87.7930 when the delatN is 10 and the DeltaE is 259.58 but i have no idea how to get the answer.

    System.Math.Tan(10/259.58) and i get 0.03854283 when the anwer should be 2.2062

    I know tan is to be raised to the neg1 exponent, is that implied in the tangent function?I can't evn get my calculato to come up with the right answer.

    Help!

    Thanks

    Completely lost in trig

    PS - i also posted this to the maths forum but i think it should be here
