I remember that - this is definite integral.

But I think I have not definite integral. I have tried to solve this problem using this pattern:

But You said mine solutions from previous posts based on this pattern were wrong.

So now I have solution by skeeter - what next ? As I understand this is some other method based on definite integral and now I can't use above pattern ? So what should I do now ? - September 12th 2009, 11:59 AMskeeter

thx skeeter - Your solution is different than solution which I know and Your solution is easier :)

As I understand in Your solution we must count definite integral and then

? Only that ?

So maybe mine pattern is for count area under curve ? I had integrals 3. years ago and I remember nothing.... :/ :( - September 12th 2009, 08:16 PMsongoku
