Answer 6

You'll need to eliminate csc x, expressing the same quantity as a function of cos x.

Let's analyze csc x: csc x = (hypotenuse) / (opposite side) = h / y, where h=hypotenuse and y=the side opposite (not adjacent to) angle x.

Draw a picture of a triangle involving angle x, showing the 'hyp,' the 'opp side' and the 'adj side.'
