    Hello, the teacher gave us this assignment in which we had to separate some variables from equations. (example: E=mc^2 for m -> m=E/c^2). I had trouble with 4 of them (the ones in the attachment), I would appreciate some help, The procedure is really important since I want to learn how to solve them.

    9. Do you know how to complete the square?

    10. Can you get thins in terms of [itex] \cos \theta[/itex] and apply [itex]\arccos[/itex] to both sides?

    11. Simmilar to 10

    15. This seems to be a trick question, the equation isn't dependent on m at all :confused:
