You only forgot to add the integration constant C.
The answer is .
Hi, my intergration is ok, but I dont know why I suddenly cant do this
I could expand it to form a quadratic, but isn't their a quicker method:
add one to the bracket power, divide the whole thing by this bracket power then divide by the diffential of the bracket... it's like the chain rule but for integration
this gives me
But that is not correct is it?
I know, but take it that im using limits Is the integration right then .. but
and in the question im doing I get the wrong answer when the limits are subbed in, yet if I expand first, then integrate I get the right answer...
the question is
if I expand the brackets and integrate I get the right answer, but If I try integrating with out expansion I get -(1/9), so I've missed something out?
