Question

∫(2+u)/(1+u²) du

anyone can help me to solve this integration??

Answer 1

Substitution method might be your best choice for this.

I suggest setting the denom as your "x"
then take the derivative: d/dx

Answer 2

i would have separated the denominator and solved them separately
2/(1+u^2) + u/(1+u^2)
...

Answer 3

can u solve it to me? help me please. im already 1 hours think how to solve it.. already forgot how to solve it

Answer 4

you can also separate them algebraictly.

Answer 5

\[∫\frac{ u }{ u^2+1 }du + 2∫\frac{ 1 }{ u^2+1 }du\]

[Constant get's factored out]
