Hi Guys,
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
to part (ii), just find the integral and see what you get
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.
recall,
where and are functions
at least tell us what you've tried before. if need be, i'll give you the solution. we just want to know that you're not just looking for someone to do your homework, but that you're actually trying. you should be able to at least do part (ii), which just requires a substitution of .
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 ?
Thanks
