We now present a group of exercises that involve the logical operators NAND and NOR. The propositionpNANDq, is true when eitherporq, or both, are false; and it is false when bothpandqare true. The propositionpNORqis true when bothpandqare false, and it is false otherwise. The propositionspNANDqandpNORqare denoted by

Prove the following. Use full sentences. Equations in the middle of sentences are fine, but do not use logical symbols. (a) (b) (n+3)2 is odd for every even integer n. It is not the case that whenever n is an integer such that 9 | n² then 9 | n.arrow_forward3. (a) (b) Prove the following logical argument using the rules of inference. Do not make use of conditional proof. Vx(J(x)O(x)) 3x(J(x) A¬S(x)) . ·.³x(O(x) ^ ¬S(x)) Rewrite the proof using full sentences, avoiding logical symbols. It does not need to mention the names of rules of inference, but a fellow CSE 16 student should be able to understand the logical reasoning.arrow_forward

The base of the cake tin has a characteristic dimension / and is illustrated in Figure 1 below, you should assume the top and bottom of the shape can be represented by semi-circles. The vertical sides of the cake tin have a height of h. As the company's resident mathematician, you need to find the values of r and h that minimise the internal surface area of the cake tin given that the volume of the tin is Vfixed- 2r Figure 1 - Plan view of the "ghost" cake tin base.
