Thanks guys, we've just started combinations/permutations/binomial theory.
I'm having difficulty distinguishing combinations questions from permutations questions and vice versa, one particular...
Just been introduced to integration by trigonometric subtitution, it's really quite something how we can use trigonometric identities to integrate an equation that seemingly has nothing to do with...

Why are we able to move from line 2 -> 3 and use u substitution?
Does it have something to do with the fact that secx.tanx = d/dx (secx)?
Thanks! Feel like there’s no real pattern with induction so it’s just the case of me going through bunch of examples and being familiar with algebraic manipulation etc.
Really struggling with proof by mathematical induction at the moment. I understand the concept, if we have a series or some theory then we can assume it in the form A(k) and then prove that A(k+1) is...
Thanks!
The pace has really picked up in second year! It's only Monday but I wish it was the weekend so I can have all that time to catch up on the work done today alone!
I'm not entirely sure how CS courses work tbh, I remember doing some magic square problem but I had to do research and it took me like a week to solve... I was just thinking how this sort of thing...
What's up, on my second year university (4 year degree) and I'm looking to switch to computer science major (from a math major), mostly due to prospective employability after I finish my...

Well I came across this on reddit: https://www.reddit.com/r/learnmath/comments/7aj9tn/calculus_1_functions/
And decided to have a crack at it since noticed it was labelled Calculus 1. But at the...

I follow the first integration but im not sure about the second.
1) Why do we need to integrate it again?
2) Where does the 1/9 come from in the second line of the...
