Question

For the differential equation find the general solution of
dydx=4y2(2<y<2)

Open in App
Solution

Given differential equation is

dydx=4y2

dy4y2=dx

dy22y2=dx

Integrating both sides
We get,

dy22y2= dx

As we know that,

dxa2x2

=sin1y2=x+c

y2=sin(x+c)

y=2sin(x+c)

Final Answer:
Hence, the required general solution is

y=2sin(x+c)
