    As

    sin(x+y)=sinxcosy + cosyxsiny

    sin(x-y)=sinxcosy-cosxsiny

    Now sin(x+y)/sin(x-y)=sinxcosy+cosxsiny/sinxcosy-cosxsiny

    Dividing numerator and denominatory cos x cos y and solving we get

    tanx + tany/tanx - tany

    Hope it help u

    Permutation is used to arrange the object and combination is used firstly to select and then arrange

    0Thank You

    Rishab Bhardwaj 8 years, 3 months ago

    Permutation is generally used at the places where we have to take the number of observation only ones where as in combination we can use a number of observation on the given set twice or the way we want. For example if I have to make a car from using red paint green paint and blue paint then I have to use permutation because I have to use only one colour out of all where is in combination if I have to make a team of 2 girls and 2 boys from 7 boys and 7 girls they can be any it doesn't matter on the boy or girl so here we use combination rather permutation.
