Hey Brilliantians, I am steeping forward towards calculus now, I know it's too much late but the hope is still there, I am really bad at calculus (hey! don't see my level , its just because of the limits :) ) I want to take my integration to good level so I need the resources on beta function, digamma function, ramanujan masters theorem and many unknown jewels to me. I am a slow learner thus I need good examples too with excellent theory. What should I need to do so? Please can you all recommend me the books too? Is brilliant wikis are sufficient, I guess they are lacking the examples. Seniors (Aditya Kumar, Ishan Singh, Pi Han Goh and many more Brilliantians) are especially bound to comment below. Also tell me the resources to learn LaTeX as I am not able to post the solution because of this.
