I'm having problem with my revision sheets - Any help would be much appreciated...
(i) Write down the general term in the power series expansion of
((x^2) - (2/x))^18
WHAT IS THE GENERAL TERM AND HOW WOULD I GO ABOUT THIS?
Hence find the term which is independant of x
I DONT KNOW WHAT THIS MEANS
(ii)Find the first four terms in the expansion of (1+x)^16 in ascending powers of x.
hence expand (1 + z + z^2) in ascending powers of z up to and including the term in z^3
DO YOU FACTORISE THIS AND RAISE BOTH PARENTHESIS TO THE POWER 16??
