= where the values of a, b and k are to be found.
As you have done we let: = and =
so
=
=
=
so a=1.5 b=3 k=9
now to evaluate this integral you can use the identity:
I'm new to this type of question and I can only get so far into the question before I don't know what to do - I haven't been taught more but I very much would like to know.
It asks:
Use the substitution = to show that
= where the values of a, b and k are to be found.
Hence evaluate .
So far I can say that = and =
=
=
=
=
And this is as far as I can get.
Could someone please help me finish the question and understand how it works from this point onwards?
Any help is greatly appreciated
