Postby Kriegerseele » 06 May 2018 10:54

Spoiler:

i got smth for you:
i need to solve two integrals with substitution and nobody in my semester got a clue how to do it. so it would be extremely cool, if some dank engineer with better knowledge than me could solve this and post it here. i need it finished at tuesday.

i wonder which of you mr sexiіs is the fastest to solve it,it probably isnt even that hard :D

Maybe this video helps? I could be wrong since it's been a while but I think this is what you're looking for. It's 100 timesb etter than all the German explanations I could find in 5 mins of googling. https://www.khanacademy.org/math/ap-cal ... -integrals

dunno whether you already know about this site: https://www.integral-calculator.com/
but it is really good for solving such integrals as it shows you the steps.
In the options you can also set the bounds if needed.

You just need to integrate those 2 and then substitute them from each other right?

I think those are two different integrals he must integrate as two separate tasks

Just noticed, doesnt really matter for the part I wrote tho, you just change 4 to -4 (because 1-x/1+x)=-(x-1)/(x+1))

if you draw that on paper you get fairly good result in 2 minutes :)

blue is the function youre integrating, and graph of similar resolution you can produce in 1 minute ez, and then you can immediately see its more than 0.5 but definitely less than 0.6 :XD

@krygr

cant rly relate to the lastest literature but what helped me alot getting back into this was "https://www.thalia.de/shop/home/rubrikartikel/ID39576646.html?ProvID=11000522". its complexe math described with ez samples. sure worth a look.
