Consider a system of equations where the ith equation is aiΦi=bi Φi+1+ciΦi-1+di. While solving this system using Thomas algorithm, we get Φi=PiΦi+1+Qi. What are P1 and Q1?

\(P_1=\frac{d_1}{a_1-c_1};Q_1=\frac{b_1}{a_1-c_1}\)

\(P_1=\frac{b_1}{a_1-c_1};Q_1=\frac{d_1}{a_1-c_1}\)

\(P_1=\frac{d_1}{a_1};Q_1=\frac{b_1}{a_1}\)

\(P_1=\frac{b_1}{a_1};Q_1=\frac{d_1}{a_1}\)
