    design a rt triangle with sides corresponding to the definition of csc, and then you can determine the missing side to fill in the other trig ratios

    or you can do a pythag method that doesnt rely on geometry

    so then 13 is the long side 5 is the short side and when added together its 18?

    almost, its good to remember that sin and csc are flips of each other so if csc = 13/5, then sin = 5/13 sin = over/hyp |dw:1361828131737:dw|

    cos = next.to/hyp = sqrt(...)/13 sec and cos are flips tan = over/next.to = 5/sqrt(...) tan and cot are flips

    so then sec and cos are the same answer tan is diffrent right?

    sec and cos use the same numbers; but are flipped versions of each other

    ok so sin i 5 / 13 then right?

    yes it might help to figure out the sqrt part, youll need it :)

    sqrt is 12

    good, then define the trig functions for me :)

    so then tan would be 5/12 and sec would be 5/13 cos would be 13/5 and sin would be 5/13

    or did i mix up sec and cos ?

    youve got the right ideas, but need practice: given: csc = 13/5 , then sin = 5/13 we know the missing side is 12 now cos = 12/13 , therefore sec = 13/12 tan = 5/12, therefore cot = 12/5
