please, can someone help me solve this:
would it be proper:
what to do now?
Thanks in advance!
It's OK to look up (or remember) a standard integral like this.
If you want to do it yourself you can use the substitution
Haha. I think you finished the problem while I was typing my post.
Apart from 12 x 1/4 = 3 of course, but really you're finished.
That's the correct idea, but you're making mistakes. Here's what I got:
We can equate all four coefficients:
Next you can solve for A, B, C, and D - four equations in four unknowns. You should get and . Now you can integrate the two functions - do you know how?
