let u = sqrt x du = dx / 2sqrt x substitute to the equation you will get, the following 2 integrate sin u du I think you should be able to take it from here.
thanks see it now
You need to put 2 outside of the integration to take care of the 1/2 that is inside the equation. If you do not put the 2 outside. The original equation would have been changed. The 2 is to prevent that from happening Hope it helps.
