Please explain how. I did not get it either.

Is the IIT-JEE form available online?

Well, I don't think that there should be any problems with the delivery of your form considering that you reside in Madras itself.

That question mark (?) was actually meant to be the dot (.) for multiplication. I don't know what the problem is but every time it occurs. Any way out?

Hello everyone!

If y = (sinx)^cosx + (cosx)^sinx,prove that

dy/dx = (sinx)^cosx. [cotx cosx ? sinx (log sinx)] + (cosx)^sinx. [cosx (log cosx) ? sinx tanx]

(CBSE 2004C)

The answer that I got was

dy/dx = [(sinx)^cosx. (cosx)^sinx] [cotx cosx ? sinx (logsinx) + cosx (log cosx) ? sinx tanx]

Kindly explain why I am getting it different. I?ll be grateful to you.

Thanks!

With regards

May be the reaction was a bit over the top! Alas! there is no delete button!

Yea, God has unconditional love and kisses only for humans. Why else would He create a world where one animal's food means other's death and put man on top of the food chain, right!

It's hard to appreciate the mercifulness and kindliness of God when I put myself in the place of the pig who was ripped apart by dogs in my locality last night.

Though the story was touching, the inclusion of God spoiled it for me.

See, downloading and saving are different in case of .pdf files. When you download a .pdf file, you can only view it as long as the browser is open on that page. When you save a .pdf file after you have downloaded it, it is stored on your computer.

So, when you have downloaded the index of the book, don't try to save it the way I instructed in the previous post. Just click the title of any chapter that you want and it will be 'downloaded'. But to store it for future reference, you have to save it the way I described in the previous post. You will have to download and save each chapter separately to get the whole book.

Don't use any browser other than Internet Explorer. The site is IE compatible only.

Merry Christmas, my dear friends! Enjoy yourselves!

Hello everyone!!!

Thank you very much for your replies. It sure has made me feel better and more optimistic. Keeping in mind what you have said, I have made a fresh foray into Calculus and it has begun surprisingly well! I have decided to use RS Aggarwal as reference material along with the NCERT textbook.

Each one of the replies deserved a salute. Your replies have lifted my sagging spirits. Thanks once again!

Be more specific. Check out the study material, you may get your doubt solved there! If not, come back!

Nice work! Entertaining, though I knew a few of them.

I have re-posted the question since did not receive enough replies the last time around. Please reply!

Hello everyone!

I am a student of Class 12 and I believe (and so does everyone around me) that I am in a miserable state of affairs in my academics.

This is my score-sheet in my half-yearly exams.

Maths - 29/100 F
Chem - 34/70
Phy - 22/70 F
Eng - 89/100 (not bad, huh!)
Hindi - 89/100 (not that bad either!)

It's not that I have been this bad all through my life. I scored 90.0 % in 10th board CBSE and 76% in Class 11 (CBSE).

But as you can see, things are pretty different now. My parents expect me to touch the 90 mark again. If only I could get my PCM up to the mark, that could become a possibility.

Everything seems so tough now. I feel like I am the dumbest person on Earth. I can't seem to understand even the simplest of concepts.

I admit to have wasted time uptil now, but that was because I have been in a state of depression since the beginning of Class 11. Now, I am ready to work as hard as I humanly can, but nothing seems to be going right.

The Pre-boards are around the corner and I am already suffering from excessive anxiety and sleepless nights made even worse by nightmares about my failing in the Board exams when I do manage to doze off. All this is making matters worse as I am not able to focus on my studies.

I am no position to even think about taking competitive exams. I just want to pass the Board exams with good ( and my idea of 'good' has gone down several notches along with my self-esteem) marks.

Do you think I have enough time to turn things around?

I haven't learned properly even a single topic of Maths so far. When I take up Calculus to study, I begin to wonder how outstandingly brilliant my previously dumb classmates have become as I can't seem to make head or tail out of it. I feel so terrible when can't get through even the first exercise of any chapter.

I do not think I have time enough to do voluminous books like RD Sharma or RS Aggarwal. I have heard that NCERT Maths textbook is good enough for Boards. If I complete each and every topic from the NCERT textbook, would I be able to fare well in the exams; or is it necessary to refer to books like RD Sharma or RS Aggarwal? At the moment, only the NCERT textbook seems like doable for me. But the question is: is it good enough?

Please help! You know how desperate I am!

Thanx dude!
