I think some of you may have seen many 0=1 proofs already. Today I am going to show you another one. So let’s begin.

**Theorem: 1=0.**

**Proof:**

Just for fun let’s integrate ,

Next we let,

Integration by Parts then give us,

Subtract the integral from both sides, we have,

add 1 onto both sides of the equation, and therefore 1=0.

Of course everyone knows zero can’t possible equal to one, but can you find where the error is? 😀

”Integration by Parts” was proved as the following….first, [d(uv)/dx]=v[du/dx]+u[dv/dx]. Now, integrate both side and we done. So, int[u dv]= uv- int[v du]. But, we have a mistake here. int(d(uv))=uv+Constant =/= uv. Of course, we are always accustomed to add the constant when we finish the integration. So, this mistake is not easy to find it

You’re right but you shouldn’t post this so soon and let others play. 🙂

ha~ agree~ i’m sorry about it.
