All right, this is the integral we have and given as a -loc x, mod x plus b over 1 plus x2 plus d.
00:07
We find the value of a &b here.
00:09
We start with here the integral, we have so it's integral x to par 4 plus 1 over x, x squared plus 1 over x, x2x2 2 squared 2dx.
00:20
Even as integral, we have x2 par 4 plus 1 over x times x2x2 square 2x2 dx.
00:31
This we have here now so now just use the partial fraction there we have so in the partial fractions like that we just get here x to power 4 plus 1 over x x x to power 4 plus 2x2 plus 1 that equals we have a over x this kind of quality equation here we have in 4 degrees so we can write it as bx plus 3 over x to power 4 plus 2x plus plus plus 1 if we have brought here so like partial fractions here we have is all this.
01:09
We get x2 .4 plus 1 equals a times 2 plus b x plus c times x.
01:13
Now to find out the x here we put x equal to 0, find the value of a.
01:16
So if x equal to 0, this will become 0...
