Life is Hard

Got it ,piece of cake, I just have small misunderstanding for something, and now it clear

This is simple 3(t^2)/2+2t But the main problem is with Fundamental calculus theorem

Actually,I am very goof in integration,but I am week in Fundamental calculus theorem, it is to me that derivative of integration will be the same function, that why I am confused. Thanks all I appreciate

Yes I did, Capital F means anti antiderivative

you You are right his answer is not logical, Thanks

The answer is 3x+2 (right)!

Thanks Could you upload refer to examples with X is the boundary of indefinite integral not numbers?

Thanks Absolutely right, but draw the function, you will see that volume is almost as his answer(using geometry not integration),and that why I am confused.

Homework Statement I have the attached problem ,and Show my answer and solution, My answer is 3.14*(15 -8ln4) While book answer 3.14(15+8ln) Can anyone point to the mistake I made?

Thank you all, The point guys is that , first integration is start from 2 and the other one is start from 8. Hence if I have only the base 2, the answer will be 3x+2 =3x+2(but the problem is the second base is 8), can't figure out what I missing till now? How can I equate them? Thanks again

Homework Statement Can anybody give me hint how to find K if F(x)= 3x+2 The integral lower part is not the same, , how to deal with his? Homework EquationsThe Attempt at a Solution Please ,I need hint to start
