Answer:
(a) The graphic representation is in the attached figure.
(b) .
(c) .
Step-by-step explanation:
(a) Given a complex number we know, from Euler's formula that . So, it is not difficult to notice that
so it is on the unit circumference. Also, notice that the Cartesian representation of the complex number is .
Now,
.
Notice that has the same modulus that , so it is on the unit circumference. Beside, its Cartesian representation is .
So, the points and are symmetric with respect to the X-axis. All this can be checked in the attached figure.
(b) Notice that
Then,
.
(c) Notice that
Then,
.
The answer would be...
R=0.51/°2
He organizes them into groups of 5, because all 3 groups can be multiplied or divided by 5.
Answer:
x+3z =7 is the equation of the plane.
Step-by-step explanation:
The line can be written as
The line since perpendicular to the plane is normal to the plane.
Direction ratios of the line are (3,0,9)
SO plane has normal with DR (3,0,9) and plane passes through (7,-1,0)
3(x-7)+0(y+1)+9(z-0) =0
3x+9z =21
