Hi
Can anyone help me with this integration.
I will use I to symbol the integer sign
Limits between 1 and 0
Ie^-x.Sinxdx
I understand I have to integrate by parts and get the following answer, ignoring the limits for the time being.
Ie^-x.Sinx = e^-x.Cosx I -Cosx.e^-x dx
then i believe i have to integrate the second part of the sum ( I -Cosx.e^-xdx)and i get.
I -Cosx.e^-xdx= -Cosx.-e^-x- I -e^-x.Sinx
Now i am stuck.
How do I combine the two answers to get a single sum which i can then put between limits.??
Thank you.
