This problem is based on tables T1 and T2 from Elmasri Figure 8.15 (this is Figure 6.15 in some earlier editions); this figure is also in the PowerPoint notes. For each of the following relational algebra queries, show the output table (no explanations needed: just show the table):

(a) T1 ./T1. P T2.A T2

(b) T1 ./T1.R T2.C T2

(c) T1 ./T1.R T2.C AND T1.P = T2.A T2
