Sorry, I meant to mention that I need to convert this to c++ visual .NET. I only learned c++ visual .NET and I'm not very familiar with some of the commands in c++ (even though they are very similar). The way arrays are arranged in that code is very different from how i learned it. Oh, and this...

I tried to convert from C++ to visual C++ .NET but got many errors. (I haven't used C in years) If anyone can do this for me, I'd really appreciate it. Please convert the following to visual C++ .NET code (to run on microsoft visual studio 2003 .NET)...

my math exam is over so i don't need to know how to solve it any more but can anybody solve this thing step by step? when i usually post a problem, many people respond, but it seems like not many people know how to solve this..

Thank you for the help.. I guess I just don't remember the properties of sinh & cosh.. I thought there was an easier way to do it because I never used cosh or sinh to solve an integral.. I guess I will get this problem wrong if it comes out on the test.. Thanks though.

I know it's very early but is there anyone who can help me?

I still don't understand how the first line became the second line.. Also, how would i use the expression Cosh^2y = 1 + Sinh^2y there? I'd really appreciate if you could tell me step by step.. I just need to know how the first line became the second line.. This is not a homework problem as you...

lol thanks for the reply but the second line is what I'm having a problem with..

http://img.photobucket.com/albums/v295/uniqness/math.jpg I'm having a hard time trying to figure out how the last two steps were taken to obtain the answer. I actually have an exam in couple hours and I would really appreciate if someone could explain carefully as soon as possible. Thanks...

thanks for the help.

http://www.isquaredonline.com/chips/1.jpg the above link is the answer to the problem I'm solving. i was wondering how i'd come up with the equation of the plane "x-y+z=0" when only the vertices of the plane are provided in the problem. thanks in advance.

hey data, i was able to understand the questions with ur explanation.. thanks a lot.. as for question 2, my professor announced that there was a typo (the + sign).. I'm looking forward to learn more from u..

For 1b, is the answer "the vector <x-x0, y-y0, z-z0> is perpendicular to r0"? as for 3, i get stuck at |u - v|^2 = 2 - 2 cos theta after playing with the right side of the equation using the half angle identity.. i don't even know how to use the definition of magnitude to solve this...

i was thinking the same.. i tried to solve that problem over and over and that + sign between |u| and |v| caused me not to solve the problem.. i think my professor might have made a mistake.. or he knows a method that nobody knows.. lol how would u solve 1b and 3? for 1b, I'm guessing (r -...

so the answer for 1a is "the set of all vectors perpendicular to r0"? or do i need to specify each vector? thanks for the help data.. i really appreciate it.. as for question 2, I've transcribed it correctly. My buddy and I spent hours trying to solve that question and gave up on it. I'm afraid...

hmmm my book says "the vector a x b is orthogonal to both a and b" i'm kinda lost.. can u teach me how to do it?
