Best ResponseYou've already chosen the best response.0\[\lim_{x\to \infty} \frac 1 {x^2} \int \tan^{1} t\ dt\]Is this your question?

Best ResponseYou've already chosen the best response.0The integral doesn't involve x, so it can be taken out. \[\int \tan^{1} t\ dt\times \lim_{x\to \infty} \frac 1 {x^2} \] tell me what's \[\frac 1 \infty=???\]

Best ResponseYou've already chosen the best response.0nope \[\frac 1 0= \infty\] so \[\frac 1 \infty=???\]

Best ResponseYou've already chosen the best response.0good :D \[\int \tan^{1} t\times 0=???\]

Best ResponseYou've already chosen the best response.0if you multiply 0 by tan t then what you'd get?

Best ResponseYou've already chosen the best response.0what ? the answer is 0 :) Ok it makes since if you put it that way but for me whos math retarded its difficult:)

Best ResponseYou've already chosen the best response.0You know the integral is a variable of t, if you integrate it and multiply by zero. You'd get zero. So it's not necessary to integrate. It's 0

Best ResponseYou've already chosen the best response.0I doubt that this is so easy. I think you have missed some portion of the question. Maybe limits on the integral. Could you check the question again?

Best ResponseYou've already chosen the best response.0its just as you put it so I think this is right but I have one more :) its \[\int\limits_{}^{} \frac{ (x^3)\ }{(x1)^2(x+2) }\] Can you help me with that?

Best ResponseYou've already chosen the best response.0What would you get if you multiply these?

Best ResponseYou've already chosen the best response.0\[(x1)\times (x1)=???\]

Best ResponseYou've already chosen the best response.0Good:) Numerator we have x^2, so add and subtract (2x+1) Could you rewrite the integral using this?

Best ResponseYou've already chosen the best response.0\[\int\limits_{}^{} \frac{ x }{2x+1 } \] Im I on the right way? I know Im not very good at this at all :)

Best ResponseYou've already chosen the best response.0I'm sorry, i thought it's x^2 in numerator Sorry. Let me think about this
