Break this up into...
The first is an arctangent and the second is a basic sub with
The second integral is a partial fractions, where you should start by dividing.
∫( 1 on the top and 0 on the bottom of this symbol) x^2+2x-5/x+3 DX
Please guys I really dont understand this. I would appreciate it if you can explain to me step by step on how I would solve these. Thanks
I cant see where I've made a mistake?
Edit- I subbed in numbers and found that yours has an error somewhere
which is not true obviously
Edit Edit (lol) -
I hate dividing polynomials, if you can I would suggest factoring which can be done in this case. Obviously not everybody will share my hatred for dividing polynomials but I treat them like the annoying cousin: when I have to go see them I will, but not a day before!The second you is a partial fractions, where you should start by dividing.
