Re: H2 Maths : Mathematical Induction Qns

1. Using your first equation and expand out, make the r^2 as the subject.

10iv) expand out for both equations in the original form(eg. when r=1,2,..,n-1,n,n+1)

Q9 2nd part you have to multiply 1/2 to the original summation to get the same form. That's why tutorial answer's denominator is twice your denominator
