  • 1/sin x - sin x = cos x/tan x
    1/sin x - sin x
    1/tan x cos x - tan x cos x/1
    tan x cos x tan x cos x/tan x cos x

    but until then I got stuck. If someone can help, then I'd be very grateful.




    I am a student in sixth form, and I am taking my Maths AS Level this year.

1/sin(x) - sin(x) = [1- sin2(x)]/sin(x) = cos2(x)/sin(x) ..... and continue....
