Vérifier quelques propriétés mathématiques de trigonométrie
Vérifions si : sec(x)**2 - tan(x)**2 = 1 csc(x)**2 - cot(x)**2 = 1
a) cos(x)**2 + sin(x)**2 = 1
cos(x)**2 sin(x)**2 1
--------- + --------- = ---------
cos(x)**2 cos(x)**2 cos(x)**2
1 + tan(x)**2 = sec(x)**2
_______________________________
| sec(x)**2 - tan(x)**2 = 1 |
|_____________________________|
b) cos(x)**2 + sin(x)**2 = 1
cos(x)**2 sin(x)**2 1
--------- + --------- = ---------
sin(x)**2 sin(x)**2 sin(x)**2
cot(x)**2 + 1 = csc(x)**2
_______________________________
| csc(x)**2 - cot(x)**2 = 1 |
