In the following question it is given that y dash is equal to x e to the power minus y.
00:07
So we can write it as d .y d x which is equal to x e to the power minus y.
00:12
So we can write it as e to the power y, d y, which is equals to x dx.
00:17
So if we take integral both the side, then what we will get? we will get e to the power y, that is half of x square plus c.
00:26
Now that is separable.
00:28
Now for second one, part b, dy, dx, which is equals to x square minus y, so it is not separable.
00:39
It is not separable.
00:42
Now for part c, dy, dt, that is ty, square.
00:47
So we will get dy by y square, that is t, dt...
