bardzo proszę o rozwiązanie tej całki ∫ | dx | |
| x2 |

f(x) = ln2x g'(x) = | ||
| x2 |
| −ln2x | −2 | −ln2x | 1 | |||||
to wyszło mi tak | −∫ | dx= | + 23∫ | dx | ||||
| 3x3 | 3x4 | 3x3 | x4 |
| −ln2x | 2 | |||
= | + | +C | ||

(ln2x)' = 2lnx* | ||

f(x) = ln2x g'(x) = | ||
| x2 |
| 2lnx | 1 | |||
f'(x) = | g(x) = − | |||
