Hi guys, in this problem, we are given a differential equation such that 4xy plus 3x squared dx plus 2y plus 2x squared dy is equal to 0.
00:23
Okay, so we have m dx plus n dy is equal to 0.
00:32
Where m is equal to 4xy plus 3x squared and n is equal to 2y plus 2x squared okay so let's differentiate partial m partial y is equal to 4x and partial n partial x it's just 4x so here we have partial m partial y is equal to partial and partial x.
01:09
So this is an exact equation.
01:13
So here we have partial f, partial x, is equal to 4xy plus 3x squared, and partial f, partial x is 2y plus 2x squared.
01:32
Okay, so on integration, omega r2.
01:36
T, y treating x as constant.
01:41
So here we have f of x and y.
01:45
It's x squared, i'm sorry, it's y squared, not x squared.
01:51
So it's y squared plus two x squared y plus h of x...
