Answer 5

Answer 6

looks like mistake ... try putting the final value on the integral equation.

Answer 7

My memory of these is starting to go hazy, but I'm inclined to agree that it's wrong.

Answer 8

so, get this:

I sit down at the exam, and this questions was question #1; i skit you not!!!

I figured it out though, thankfully pretty fast.

\[(\tau - t)^3 = -(t - \tau)^3\]

That was it...lol. the solution manual is right.

Thanks for replying though ^_^

Answer 9

actually, it was (tau - T) on the test. not sure why not in manual though.

i can't believe it was the exact same question!!
