1. ## The most complicated problem in Derivative of Inverse Trigonometric Functions

Hello everyone, i'm new in here . I do hope I'm welcome in here. Pls.. give me some complicated, not basic, really complicated problems in derivatives of inverse trigonometric.. If possible pls. post it asap... many thanks

May I ask why? Or, does the name say it all?

BTW I am an MHF Ambassador, and as such, I speak on behalf of the forum when I say:

"Welcome!"

Why not consult your text book?

Go to the library and find calculus books. Each book will have examples of what you're looking for. Try also searching the Calculus subforum. And I also suggest you try using Google. And, what the heck, perhaps you could ask your teacher too.

5. Ok, Ok... I'll give him one.

This isn't that difficult, but try this and we'll see where you're at.

$\displaystyle \int\frac{1}{\sqrt{x}\sqrt{1-x}}dx$

Try that on for size.

Ooops he said derivatives... I'm not a very good listener.

Show that

$\displaystyle \frac{d}{dx}\arcsin{x}=\frac{1}{\sqrt{1-x^2}}$ .

6. actually i have browsed and photocopied exercises in books in our library.. But the problems are so easy,... but when our professor gives an exam... It's so difficult as compared to the problems in the books.. Pls.. give me a set of problems thanks.

As I said earlier, ask you Professor (that's part of his job). Also, past exam papers should be available (ask your institute's library, which is where they are usally archived) for you to work through.

We don't have time to construct difficult questions for you (and how are we to know what is easy, difficult and impossible for you anyway. Everything is relative.) and we don't have time to write out solutions to such questions (which I assume you would want when you got stuck).

The main purpose of MHF is to help people with questions thay can't do, not to provide an extension program for people who already understand the work and don't really need help.

9. Students are constantly complaining that the problems on the test are harder than the homework problems. Actually professors typically make an effort to see that most of the test problems are easier than most of the homework problems.

What they really mean is that on a test they don't have the text book open, or the answer in the back of the book, or friends working with them, etc.
