rozpisz ctg 5x = | ||
| ... |
| cos5x | ||
to będzie sin3x * | = | |
| sin5x |
| sin 3x * cos5x | ||
lim | = | |
| sin5x |
| sin3x | ||
lim | * cos5x = | |
| sin5x |
| 3* sin3x3x | |
i nie wiem co z tym cos5x | |
| 5*sin5x5x |
| sin ax | a | ||
−−> | gdy −−> 0 | ||
| sin bx | b |
| 3x | 3 | ||
, ale dlaczego cos (5*0)= 1? | |||
| 5x | 5 |
| sin 3x | 3 | |||
dalej bedzie limx−>0 | * cos 5x= | |||
| sin 5x | 5 |
