Thx! Thx To All WHo help ME to do my Home Work! U`re a very good persons and Very very Clever. And I don`t know why a lot of XXXXX say that USA - And Americans are very ... O don`t think so... U are very friendly people and can help other people in any time. One more thx. If i would have some...
Really? Or i`m full idiot or u are great scientist! =)
I have variant \int \frac{dy}{y} = \ln|y| + C = \ln |\sec(u) + \tan(u)| + C and want to complete it, but i`m interesting in u`r variant of solve too... =)
Agrrr:mad: See post 63! =)\int \frac{du}{u} = \ln|u| + C = \ln |\sec(x) + \tan(x)| + C I have the same but how to solve "\int \frac{dy}{y} = \ln|y| + C = \ln |\sec(u) + \tan(u)| + C" if x=2tgu
about 7: ... = \int \frac{du}{1 - u ^ 2} = ... By what formula i must integrate? becouse i can`t find it..
P.S. Maybe nobody in my group don`t know integrals like me now couse for this day i learned so much..
