Question

Show using definition of Θ that 1/2 n² − 5n = Θ(n²)

Answer 1

Answer #1

ie To prove & -50 = 0 (m²) c. n < n - Snagin? for proving the first part i.e. ca finding some value of C, sit. c.no sn .sn If

0 1 5 5 ( 1 ) n. 1.3

We can decrease the value of C1 further but it'll give us looser bound.
