    hey real amateur needs help with trigonometry function

    hi,

    I have a litlle problem here. Im studying at uni and there is a subject called programming with c/c++. As i have this subject once every two weeks I get to do one laboratory work each time.

    So few minutes ago doing usual stuff by the computer I looked up the sedchule of my lessons and I saw that i have to make a programm for tommorow ( well like 4 hours left till I go to uni... )

    Programming for me is really a new thing and I dont understand almost nothing in it ( i just know very basics of it ).

    So I am asking anyone who would like to help me to write as simple as possible code for this function using C...

    tg(x)+-tg(y)=(sin(x+-y))/(cos(x)*cos(y))

    x and y must be typed by the user and the answer should come in degrees

    please guys if you are master in this it should be easy for you i think

    I guess you missed the Homework policy, huh? No one's going to do your homework for you (well, maybe Adak will) because you forgot about your assignment.

    oh yes, it's very simple, which is one of many reasons no one here will do it for you

    That's not a function.
    A function would be denoted much like this:
    tg(x, y) = ...

    You have to make a start, then post what you have, and hope someone is kind enough to give you some useful hints.

    I’m happy to show you how to do this if it’s not too late.

    So even though you really don't know anything about programming, you should pass? Come on now.
    It's a shame that you thought you had more time. It stinks, and it's annoying. But that still doesn't justify you passing something without actually knowing what you're doing.
    Life is hard. You didn't learn what you were supposed to do, and we cannot help you with that. We're not going to help you cheat.
    If you still want to learn despite failing your assignment/test/whatever, then we'll help you. But we're not doing your homework.

    You'd be surprised how many people have more than enough time to complete an assignment and fail to do so. In a few classes, I have had people begging me to do homework that isn't even hard. One guy paid me 20 bucks each time I did one of his assignments.

    Yes, and one day, they will be your boss (earning more of course).

    They´ve obviously mastered enough social engineering skills to talk others into doing what they´re incapable of doing for themselves.

    If you know "how", you´ll have a job.
    If you know "why", then you´ll be the boss!
    If you dance barefoot on the broken glass of undefined behaviour, you've got to expect the occasional cut.
    If at first you don't succeed, try writing your phone number on the exam paper.

    I wouldn't exactly call this social engineering. He simply asked and offered and I accepted. The work wasn't even difficult or lengthy at all, and I could have used the money. It's not as if he manipulated me. Thank you very much. I would say that he didn't know "how" or "why".


    If someone doesn't know "how" then I'd suspect they wouldn't be a very competent boss to begin with.

    Off topic, a little....

    I had the privilege of meeting a person during my youth which came to mind while reading about the competencies associated with the "how" and "why" assets. This individual had a plaque hanging over a door way that read: "If you're so dang smart, why ain't you rich?"

    Altec, post some code and turn it in to the university late. That way you can get some time on the compiler, and some great advice from some great scientists/engineers for the next class meeting. All the rhetoric gets old really quickly, especially since the forum policies are clearly posted on the programming board....

    Where may I ask are you attending? You posts seem to have been translated. I was considering some of the programs in Illertissen, and I even thought about St. Andrews for a little while. The University of Mississippi had an excellent Masters of Art in Mathematics program, but I'd have to get to work on Russian or French to go with the German...seems the history of mathematics has much from which to gleen.
