NB : on omet la constante d'intégration c.
∫ | 1 / | dx = (2/a)ˇ |
∫ | x / | dx = |
∫ | dx = | (2/3a)ˇ |
∫ | xˇ | dx = |
∫ | 1 / | dx = | ln |x + | | |
∫ | x / | dx = | = | -(1/a)ˇ arcsinh (a/x) |
∫ | 1 / (x2ˇ | )dx = - | / (a2x) |
∫ | dx = | (x/2)ˇ | + (a2/2)ˇ ln |x + | | |
∫ | xˇ | dx = (1/3)ˇ (x2 + a2)ˇ |
Quand |x| > a :
∫ | 1 / | dx = ln |x + | | |
∫ | x / | dx = |
∫ | dx = (x/2)ˇ | - (a2/2)ˇ ln |x + | | |
∫ | xˇ | dx = | (1/3)ˇ (x2 - a2)ˇ |
Quand |x| < a
∫ | 1 / | dx = arcsin (x/a) |
∫ | x / | dx = - |
∫ | dx = (x/2)ˇ | + (a2/2)ˇ arcsin (x/a) |
∫ | xˇ | dx = | -(1/3)ˇ (a2 - x2)ˇ |
∫ | / x | dx = | - aˇ |
