he took out the common factor of (n+1)! edit: nvm people already answered it -.-

THey need school rank

Sorry, I don't have an estimate myself but how would this be ~94...

Wow, okay. Thanks heaps :] Does anyone know how to do the first bit of part 1 without evaluating the limits 0-1 of f^-1(x)?

Embarrassing but, how do I make y the subject... ?

again

I might update this thread with questions on top of this one later on that I can't figure out. 1. F(x) = 2x/(x^2+1) -1<=x<=1 (<= is less than equal/greater than equal) Calculate the total area of the two regions enclosed by y = f(x) and y = f^-1(x) Now, the next part asks you to evaluate...

ahh, to be honest I havn't looked at any 4U past questions on mechanics so I didn't know that they would supply the equations/ask you to derive it specifically. Thanks :]

Sorry, for example, in 4U: A particle is projected under gravity from a point O. Prove that the horizontal distance between the two points on the path of the particle, which are at a vertical distance above O equal to 1/n of the greatest height, H, is R[(1-(1/n))^1/2] where R is the horizontal...

That is true but some questions don't require you to derive the formula and rather just spit it out... EDIT: Which, I guess, would make it much easier and faster when answering a particular question like that.

Hey, Just wondering if anyone had any tips for recalling the formulas for this topic.. There are so many formulas and their nothing like the parametric ones :/ Thanks.

Haha, that was actually funny

Nice GIF :] *Takes*

What is... tabular IBP? Edit: NVM. Used google and I think it is integration by parts??

this.

Ohhh, I'm so stupid haha. Thanks :]]

So I worked out the recurrence formula for this question for someone else (I had done it before). Answer, however, has a positive 2nd coefficient and negative 3rd, 4th coefficient. Why? Thanks :]
