You should be familiar with the basic logical operators: if P and Q are propositions, i.e., statements that are either true or false, then you should understand what is meant by (1) not P (2) P or Q – the mathematical use of “or” is not exclusive so P or Q is true even if both P and Q are true. 47 0 obj (Lecture 17 - Some Special Functions and Differentiation in Several Variables) 51 0 obj << /S /GoTo /D (subsection.1.1) >> endobj 91 0 obj << /S /GoTo /D (section.5) >> 1.
