L = (1−sin x)( | + tg x) = | |
| cos x |
| 1 | sin x | |||
(1−sin x)( | + | ) = | ||
| cos x | cos x |
| 1+sin x | ||
(1−sin x)* | = | |
| cos x |
| (1−sin x)(1+sin x) | 1−sin2 x | cos2 x | |||
= | = | = cos x = P | |||
| cos x | cos x | cos x |
Czy mógłbym jeszcze prosić o ten przykład: sin2α −cos2α / sinαcosα = tg2α−1/tgα
| 1 | ||
P = tg2 x − | ||
| tg x |
| tg2 x − 1 | ||
P = | ![]() | |
| tg x |
| sin2 x | sin x | |||
P = U{ | − 1}{ | = | ||
| cos2 x | cos x |
| sin2 x − cos2 x | sin x | ||
U{ | } = | ||
| cos2 x | cos x |
| sin2 x − cos2 x | cos x | ||
* | = | ||
| cos2 x | sin x |
| sin2 x − cos2 x | |
= L | |
| (sin x)*(cos x) |
To rozwiało moje wątpliwości
