question:
4. Suppose there are n lines in the plane, no two are parallel and no three are intersecting at one point. Into how many regions is the plane divided by these lines? Let n) denote the number of regions the plane is divided into by 11 lines. Do the following. [a] Compute the values for n} for n. = 1.2.3.45. {In} Give a conjecture on the formula of n). to} Justify the conjecture using induction. 3! = 3.2.1 Proof by Induction . h Conjecture 2' = 2 for all integers r nz4 (in ! > 2 " 2 2. = 2 2 = 4 Proof You show that * Is 3. = 4 12 = 32 6 n! = 4! = 4.3. 2.1 = 24 6! = 720 > 2) = 64 10 24 = 2.2.2.2 = 16 . 7 7! = 3,040 2 2+ = 128 (?)8 40, 328 X 2521 thus , $ is true for 1= 4 : 8! that is, n! > 2" for n= 4.
