    Hi,

    The question is:

    Solve the equation: arcsin(x/x-1) + arctan(1/x+1) = pi/2

    I have no idea on how to start it. If anyone can give a detailed solution or show some basic steps which would help me complete the question.

    Thanks

    look at Q50 and Q51 in the following PDF for similar ideas

    PS
    this is a standard equation that I come across with students at least once a year.
    I strongly suspect that there should be a 2 in front of the arctan...

    well I was just given that. But like even if there was a 2 given, I would have still struggled. Any advice on how to concrete these concepts in my brain?

    If you are asking me "how to see it", the only answer I can give you is practice.

    I can sincerely tell you when I learned these at A level I was struggling too
