Homework Statement
This is not a homework but since asked me I'm posting it here. I know how to intergrate by parts and can do this using formula
But I'd like to do this using the tabular method
Question
Integrate xcos(x^2) using tabular method
Homework Equations
The table with derivative on one volume and integral on the other column
The Attempt at a Solution
I know we can differentiate the one which is harder to intergrate so I integrated the x and differentiated cos(x^2)
So I get -2sin(x^2) for the derivative column and (x^2)/2 on the intergral side
When I multiply the results as said in tabular method and integrate the last portion, I get
(X^2)/2 * cos(x^2) -2 integrated by sin(x^2) * (x^2)/2
