9x-7i 3(3x-7u)
Input |
---|
9 x – (7 i) (3 (3 x – 7 u)) |
Result |
9 x – 21 i (3 x – 7 u) |
Alternate form assuming u and x are real |
9 x + i (147 u – 63 x) |
Root |
x = (343/150 – (49 i)/150) u |
Property as a function |
odd |
Root for the variable u |
u = (3/7 + (3 i)/49) x |
Derivative |
(d)/(dx)(9 x – (7 i) (3 (3 x – 7 u))) = 9 – 63 i |
Indefinite integral |
integral (9 x – (7 i) (3 (3 x – 7 u))) dx = 147 i u x + (9/2 – (63 i)/2) x^2 + constant |
Definite integral over a disk of radius R |
integral integral_(u^2 + x^2 |
