Im sure my teacher aint taught me everything for exam in January, thank god for this site.
I have worked out part a) which is: Write down the first four terms in the expansion of (1+ x/2)^5 in ascending power of x. I got 1 + 10x + 40x^2 + 80x^3.
So how do i do the second part? Question: By subsituting an appropiate value for x in a), find the appropiate value for 1.05^5. Show all working and give you answer correct to three decimal places.
Need help. again -_- Watch
