GheyCouldn't do the ghey integration q16 and the ghey 3 marker inequality questions (16bi) gheyyyyy
Add one, minus one for the numerator. Then you can split it. You end up getting the original integral twice and you use IBP for the last bit so the answer is x/(1+lnx) iircA lot of questions required a lot time to do eg. the graphs that Carrotsticks is mentioning about. :/
Not feeling the best about this, quite difficult I must say.
Still think I can get a 70 raw but that may be farfetched
Anyone have the solution to the last integration?
Find the integral of lnx/(1+lnx)^2 dx
Is it a substitution of some sort?
Wow nice. I tried staring at it for 10 minutes but still couldn't get it :'(Add one, minus one for the numerator. Then you can split it. You end up getting the original integral twice and you use IBP for the last bit so the answer is x/(1+lnx) iirc

I did that but I couldn't integrate 1/(lnx+1)^2Add one, minus one for the numerator. Then you can split it. You end up getting the original integral twice and you use IBP for the last bit so the answer is x/(1+lnx) iirc

You had to move it to the other sideI did that but I couldn't integrate 1/(lnx+1)^2
I tried u = lnx, and x = e^(u) and IBP, but alas i did not succeed, and doubt I will get any marks for workingAdd one, minus one for the numerator. Then you can split it. You end up getting the original integral twice and you use IBP for the last bit so the answer is x/(1+lnx) iirc
