I do not remember exactly but I had two favorite problems when I was about 6. Figuring the area under a curve and fitting data with polynomials.

When you were 6 yrs old, you did these kind of problems. Well, don't joke. There is also a limit for telling lies, bumpkin.

I could calculate very rapidly in my head and loved to do so. I had little understanding of calculus or numerical analysis but those two problems fascinated me. I discovered on my own how to stuff rectangles under curves and in a primitive way I was doing calculus. The curve fitting problem stumped me until much much later...

Well, bobbym if you are so intelligent then I think you could have easily done those difficult problems which I had submitted before here.

I did some and could not do some others, that is about the limit of my intelligence.

You can not, since I haven't posted them only. I can do if you ask me to.

Hmm, where does gAr teach?

Is it possible that I have met him already?

Excellent Bobbym. The answers of 11,12,17 i)&ii) and 18 i) are correct. C'mon try to solve the rest of them.

*Note:-I must tell you all that these answers are open for all to solve. I do not want only bobbym to solve it, other users are also welcome to post their answers here.*

Hi;

I will try some more but I am preparing to move and this is occupying lots of my time. I will be a bit slower than usual.

Hmm, your 15 and 16 i) answers are wrong. The 16 ii) answer is correct.

Where are you moving, bobbym? Not from Florida to New York I hope? Anyways take your time, get the work right done and come back soon.
