Best ResponseYou've already chosen the best response.0\[2\int{dx \over x^2 + 3}\]That's tricky stuff: trig substitution.

Best ResponseYou've already chosen the best response.1if you have \[\int\frac{2}{x^2+1}dx\] then just recall that \(\displaystyle\frac{d}{dx}\tan^{1}(x)=\frac{1}{x^2+1}\) and therefore \[\int\frac{2}{x^2+1}dx=2\cdot\tan^{1}(x)+c\] if you want \[\int\frac{2}{x^2+3}dx\] then, if you want, you can use the substitution I gave above

Best ResponseYou've already chosen the best response.2so if 2/(x²+1) = 2tan^1(x/root1) all over root 1 2/(x²+3) = dw:1350487017539:dw

Best ResponseYou've already chosen the best response.2LOL thank you! always forget the C... would i lose a mark for not putting +c if i do not need to figure out C?

Best ResponseYou've already chosen the best response.1there will be a time in the future when you will find a value for C. Particularly when doing initial value differential equations
