1. Find the coefficient of $x^{10}$ in the power series. $\left ( 1+x^{2}+x^{4}+x^{6}+x^{8}+.... \right )\left ( 1+x^{4}+x^{8}+x^{12}+.... \right )\left ( 1+x^{6}+x^{12}+x^{18}+.... \right )$ Ans. $\frac{1}{\left ( 1-x^{2} \right )\left ( 1-x^{4} \right )\left ( 1-x^{6} \right )}$........now not able to proceed. 2.Provide a closed formula for the sequence it determines x2+3x+7+(1/(1-x2))

There are Three processesP1,P2,P3 sharing a semaphore for synchronizing a variable, Initial value of semaphore is one. Assume that negative value of semaphore tells us how many processes are waiting in queue. Processes access the semphore in following order a. P2 needs to access b. P1 ... critical section e. P1 exits critical section The final value of semaphore will be 1. 0 2. 1 3. -1 4. -2
