Hi all. I am having Calculus 1 this year. We are using a book called Thomas Calculus.
I think its a lot of fun, but I have to work very much since there is basic stuff like trigonometry that I know really bad. Since I work so much with math I thought it could be fun and helpful to talk with other math people in here:-)
To the question:
∫ (5x)/(3x^2+5) dx
What I did was this but I think its too complicated:
∫ (1/(3x^2+5)) * 5x
Integration by parts give.
(5x) ln(3x^2+5) - 5 ∫ ln (3x^2+5)dx
Not sure have to calculate the last integral. Not sure about anything here really..
