Question

Below are ten differential equations. Some can be solved by the separable variables method
and some others don't. You don't have to solve any of them. For each one, just classify it as separable or not
separable and justifies in the case of separable variables showing how the DE can be solved.

Note: Solve what is requested for the 10 equations, as shown in the example

 

Example : y' = xy
Answer :
Separable, = x dx

1.y' =
1. y' :
2. y' = x +y
3. y' = Ln (xy)
Ln x + x
Ln y + y
5. y' = ye#inx+cosy
6. y' = Ln (x³)
7. y' = sin(x')
8. y' = y sin x + xy
