About LinkBacksi need to know the integration formula for double components like integration of u*v......plz suggest
Just in case a picture helps...
... is lazy integration by parts, doing without u and v.
... is the product rule. Straight continuous lines differentiate downwards (integrate up) with respect to x.
See here.
The formula, of course, (one version, anyway) is
But the important thing is to see how it depends entirely on working backwards through the product rule for differentiation.

It's pretty easy to derive.
The product rule says that, for two functions u and v in terms of x,. Integrate both sides with respect to x to obtain
Rearranging, we get the integration by parts formula,(you can add an arbitrary constant).
