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.
Always satisfy the Prime Directive of getting the right answer above all else.

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.
Difference betw dy and delta y
Delta y,
is the change in y over any interval. dy is the change in y over an infinitesimal interval.In mathematics, you don't understand things. You just get used to them.

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.
