Sorry to bother you again. Please look at the question below. I only managed to find part (i). Please advice me on how to find part ii and iii. Thanks for your help
can you continue?
for part (iii). notice that the sly devils let you calculate the derivative of one of the functions in the product and the integral of the other function in the product. this is exactly what you would do for integration by parts. so that is what you want to use here.
where and are functions
for part (iii), i gave you the formula. here, and . part (i) asked you to find and part (ii) asked you to find . just plug them into the formula i gave you
Thanks CaptainBlack for the help. I did try before and i do not know how to do it.
Is there any other ways to solve this problem? Could we use this way.
Can anyone guide me how to use this way to solve this problem ?
