    Section 5.4

    I need the formula for the following:

    csc(u - v)

    sec(v - u)...Why did the author exchanged places between v and u. In other words, why not
    sec(u - v)? See the difference?

    I also need the formula for cot(u + v).

    I need the formulas for all the above to do

    Ok. I did not forget the sign. I made an error along the way. I will give myself credit, though. So, take away 2 points and give me 3 points for effort. I will do 44 and 46 tomorrow, Lord willing.
