Equation, y prime, which we can raise d, y, d, x, equals 1 over x times square root of 4x squared minus 9.
00:19
So we want to use the separation of variables method.
00:23
So i'm going to multiply first both sides by dx to separate the y's and the x's.
00:28
So i get dy equals the right -hand side times dx.
00:39
So now we can take the integral of both sides.
00:43
Integral of the left -hand side is just y.
00:46
And we'll add in the constant on the right -hand side.
00:49
So y equals the integral of 1 over x times square root.
01:00
And we can rewrite this integral as 2x squared minus 3 squared, dx.
01:14
So now i am going to multiply both top and bottom by two.
01:30
And you'll see why in just a second.
01:33
So let's just multiply top by two and multiply bottom by two.
01:40
So we get 2x square root of 2x squared minus 3 squared...
