In Problem 11, find $v\left(x\right)$if$v=0,x=1,$at$t=0$. Then write an integral for$t\left(x\right)$.

Find the general solution of the following differential equations (complementary function + particular solution). Find the particular solution by inspection. Also find a computer solution and reconcile differences if necessary, noticing especially whether the particular solution is in simplest form.
