Answer:
<h2>6cis120°</h2>Step-by-step explanation:
The general form of a complex number z = x+iy
If x = rcos and y = rsin
where r is the modulus of the complex number and is the argument, z in polar form is represented as:
z = rcos+ rsin
z = r(cos+ isin
)
z = rcis
Given the complex number z=−3+3√3i
r =
since the argument is negative and tan is negative in the 2nd and 4th quadrant,
In the second quadrant, theta = 180- 60 = 120°
On substituting r and theta, the complex number in polar form is expressed as 6cis120°
y squared equals x squared minus z squared.
Solution:
The given triangle is a right angled triangle.
Hypotenuse = x, Base = y, Height = z
Using Pythagoras theorem, we can find the lengths of the sides of the right triangle.
Pythagoras theorem:
In right triangle, square of the hypotenuse is equal to the sum of the squares of the other two sides.
Subtract from both sides of the equation.
Switch the sides
y squared equals x squared minus z squared.
Hence Option B is the correct answer.
