Let x and y be functions of t. Find the general solution of the system of equations below by first converting the system into​ second-order differential equations involving only y and only x. Use a computer system or graphing calculator to construct a direction field and typical solution curves for the given system.
x′=−4y, y′=16x
Solve for
x(t).
Choose the correct answer below.
 
 
A.
x(t)=Acos(8t)+Bsin(8t)
 
B.
x(t)=Ae8t+Be−8t
 
C.
x(t)=Ae16t+Be−16t
 
D.
x(t)=Acos(16t)+Bsin(16t)
 
Now find
y(t)
so that
y(t)
and the solution for
x(t)
found in the previous step are a general solution to the system of differential equations.
 
y(t)=nothing
Use a computer system or graphing calculator to construct a direction field and typical solution curves for the system.
