Homework Answers

Answer #1

First equation is variable seperable. So we can easily get solution of this equation.

After puting value of x in second equation, it becomes linear differential equation in variable y. So find integrating factor . And now you can get solution of this equation easily.

So, solutions are:

x = c1et

y = 4c1et + c2e2t

where c1 and c2 are constants and x and y are functions of variable t. (Assumed)
