Hello goursiddhant
I hope you are doing good. I would like to tell these types of questions which generally have two variables in multiply can be solved by product rule. I would you to go through concept of product rule first which says
d/dx (u.v)= (d/dx(u)).v+(d/dx(v)).u
so by above formula
d/dx(x.sinx)=(d/dx(x))sinx+(d/dx(sinx)).x
= 1.cosx+cosx.x will be the answer
If you have any other doubt then you can always reach us to clear them :)
we are always available to help you out and guide you
Thankyou
