Answer:
Step-by-step explanation:
From the differential equation given:
The equation above can be re-written as:
Let assume that if function M(x,y) and N(x,y) are continuous and have continuous first-order partial derivatives.
Then;
M(x,y) dx + N (x,y)dy = 0; this is exact in R if and only if:
relating with equation M(x,y)dx + N(x,y) dy = 0
Then;
So;
Let's Integrate with respect to x
Then;
Now, we will have to differentiate the above equation with respect to y and set ; we have:
Hence,
Finally; the general solution to the equation is:
