Hej Mam pytanko jak obliczyć pochodną z f(x) = | ||
| x2 − 2x + 2 |
| f | f'g −fg' | |||
( | )' = | |||
| g | g2 |
| x2−2x−2 | x2−2x+2−4 | 1 | ||||
= | = 1 − 4 | |||||
| x2−2x+2 | x2−2x+2 | x2−2x+2 |
| (2x −2)(x2 − 2x +2) − (x2 −2x −2)(2x − 2) | ||
f'(x) = | = | |
| (x2−2x+2)2 |
| (2x−2)(x2−2x+2−x2+2x+2) | 4(2x−2) | ||
= | |||
| (x2−2x+2)2 | (x2−2x+2)2 |
