    I really don't understand what this question is asking you to do please could someone explain for me!

    The finite region bouded by the curve with equation y= (1/(x-3))-(1/(x-1)) and the lines x=4 and y=0.25 is denoted by R. Show that the area of R is


    This might help.
    Basically the stipulation is that the area R is to the right of x=4 and above y=0.25 (as otherwise the area would be infinite). Clearly y=0.25 at x=5 and there is no area above y=0.25 at x>5, so x=5 is the upper limit on the first integral.
    The second integral subtracts the area below the line y=0.25 for 4<x<5, as the first integral finds the area bounded by the curve and x axis [note you could also have simply found the area of the rectangle instead of doing an integra[.
