where did i goof up? i'm doing Riemann form of the definite

By taking n out of (n+1)^2 you brainlet

>>8550574
but how else do i cancel out n^2? this is what the book does.

>>8550577
Yeah but it's n^2 not n, so n^2(1+1/n)^2 is on the top and you get the thing you expected

>>8550580
ah i see, i apologize for my stupidity. i didn't keep into account the power while factoring.

>>8550584
Don't worry Senpai, and don't give up

>>8550580
so while this thread is up, wanna talk about mathematics?

>>8550588
I'm but a lowly physicist, pretty much a 100 iq equation monkey

>>8550588
Yes. Does a "positive" Hessian matrix of a two-variable functions implies that this function admits no maximum ?

>>8550591
i thought physics was ripe with math, like path integrals and gauge theory.

>>8550615
Not him, but the tools used in physics are usually less rigorous than in Math.

It's not usual to treat da/dt as a fraction to resolve differential equations easier.

why of course not, wtf anon
