Alejandro The Great :
my ability to believe the expression we get back here is severely hindered by the fact I don't understand any of this

I used to resolve problems like this for breakfast, but then I became a software developer and now this sounds like …somebody that I used to know…

Tik Toker :
what level maths would this be??

tlys :
Alternatively you can trig substitute with i*sin(t) then you get the indefinite integral as sinh^(-1)(x) :) sinh^(-1)(1/2)=ln(ϕ)

“Phee”? Thought it was “Phie” (like “lie”)? 😁

The Irish Physicist :
I would just see that this integral is the derivative of Sinh^-1(x) and you can sub in

I immediately thought of the hypotenuse of a triangle. Tangent because you can do O/A which you can make x*2

CarlosVL_1999 :
now I miss integral calculus instead of learning Navier Stokes equations

Would the sqrt(sec^2(u)) not become |sec(u)| instead of cancelling out?

@Nahian Khair @shadab @Koolguy pretty easy

i thought i was good at math until i took calc 🤪

Took one look at the equation and got war flashbacks

I plugged into a calculator and it gave me the answer as inverse of hyperbolic sine of 1/2 which had me thinking why that's equivalent to ln((1+√5)/2) and I found the answer sinh(x)=(e^x-e^(-x))/2

when I saw no trigonometric functions in the original but then trigonometric functions came anyway 😭

FermatsFirst :
I could never have solved this myself, but I'm very proud of the fact that I completely followed every step, even tho I haven't done calc in 40+ yrs.

Yeah that’s what I was thinking too
