a Find a evaluation for the function (4n+1)8log(n2). (Hint: 8log(n2) can be written in a simpler way.) b Give an example of two functions t1(n) and t2(n) that satisfy the relations: t1(n)= (n2),t2(n)=(n2) and t1(n)t2(n)=o(n2). c Give an example of a function t1(n) such that t1(n)=(t1(2n)). d Give an example of a function t2(n) such that t2(n)=o(t2(2n)). (Note: For (b), (c), (d), seek your examples among polynomials, logarithms, exponenials, factorial.)
