Question

For the differential equation find the general solution of
dydx=sin1x

Open in App
Solution

Given differential equation is

dydx=sin1x

dy=sin1xdx

Integrating both sides
We get,

dy=1.sin1xdx

Using Integrating by parts:

f(x)g(x)dx=f(x) g(x)dx[f(x)g(x)dx]dx

Take f(x)=sin1x and g(x)=1

Putting (a) in (i) then we get,

y=x.sin1xdu2u

y=x.sin1x+121u2dt

y=x.sin1x+12u12+112+1+c

y=x.sin1x+u+c

Now, putting the value of u=1x2 then we get,

y=xsin1x+1x2+c

Final Answer:
Hence, the required general solution is

y=xsin1x+1x2+c
