(sinx-xcosx)/(xsinx+cosx) .

No specific question as to what is to be done with the above ratio.

To find the value of the expression as a ratio, we need to put x=some angle and evaluate the ratio.

The expression is already in a form and does not require any simplification.

The limit of the expression at pi/2 is 2/pi

The limit of the expression when x=0, is zero clearly.

You can ask for any further help related with this.
