Don't usually eat wedding food as I've noticed it's particularly carb dense, but I'd have to say once there was a pretty decent chicken/avo salad

Last 3 songs you listened to?

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...

Can someone help with 5.3 ive done the previous 2 but not sure how and where to start with 5.3...

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.

We started doing...

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!

We just started proofs...

Thanks for the response, we just learned about proof by contrapositive today.

I'm starting to wonder, we've embarked on set theory but in our final exam there is no set theory?
So I'm thinking...

Been a while since I've posted here, hope everyone's well

So, I asked my professor why the empty set is a subset of every set and he told me that it is just a truth in mathematics, and I sort of...

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...

Finally finished calculus i course, starting calc ii in the new year!
edit: will probs take a look at:

since have 3 months of holidays...
As...

No, only in runescape

Do u appreciate dark humour?

For example if you have to integrate e^x^2, surely u can just keep on integrating it?

Also, nearly finished Calc I course. Got ahead of myself and a past paper for course im doing next year, looks...

So Integration by parts.
When do you stop integrating? I find that you can literally keep on going. Where do you stop?

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...

Oh I thought we were integrating e^3x.

Also why do i get an error when integrating e^-x^2

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...
