Re: Integral

What does &Y mean?

In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.

Re: Integral

Hi;

thickhead: If you do not want to answer a post that is your choice. But when you do try to remember that you are talking to a human being and a member of this forum as you are. Posting smilies back at people to taunt or ridicule ( I removed it ) can hurt someone's feelings. Please do not do that anymore.

Delta y,

is the change in y over any interval. dy is the change in y over an infinitesimal interval.

Re: Integral

Hi Zeeshan,
I am sorry if you have been offended. I had every reason to believe  you were pulling my leg.You only had given me the value of x=3 ,not chosen by me.
In addition taking dx=0.02 does not confirm to its being infinitesimal. So that may not be what is expected.
