ahh, statistics! the joy it has brought... up until now.

i have a (uber-late) midsemester late this week, and i'm going alright, except for the proof-type questions that he said there will be one of on there, i have no idea even how to start them, i've never come across them until now.

can anyone atleast get me started?

If i have W = arctan(T/sqrt(k)) where T =d= t(k) (t-distribution, k degrees of freedom)

show that W has pdf g(w) = c(k) cos^(k-1) (w)

(where c(k) has c subscript k, and where (w) is the argument of cos^(k-1)
