    Need help once again

    I'm pretty sure I'm suppose to take tan on both sides but then I'm kinda stuck, assistance will be appreciated!


    Much thanks

    I looked at it quickly and you can probably use the tan special angle formula with tan(a+b) = [tana+tanb]/(1-tanatanb). Can't see a faster method for now.

    That's correct. You use the formula repeatedly.



    etc etc

    I have used arctan instead of tan-1 to save tedious LaTeX input.
