What does p and q mean
What does p and q mean-And qis false However, if pis true and qis false, then p^qwill be true Hence this case is not possible Case 2 Suppose (p!q) is false and p^qis true p^qis true only if pis true and qis false But in this case, (p!q) will be true So this case is not possible either Example 10 Find the vector joining the points P(2, 3, 0) and Q(–1, –2, –4) directed from P to Q Given P (2, 3, 0) Q (–1, –2, –4) Vector joining P and Q
